StackOverflowError This error is thrown when a stack overflow error occurs within the virtual machine. The exact problems would be off-topic here, you can google them... –KLE Oct 1 '09 at 9:50 add a comment| up vote 3 down vote I use IllegalArgumentException relatively often. ClassCastException is thrown when an object fails an IS-A test with the class type it is being cast to. For example, say class A refers to a method in class B.

I often use assert for those, but illegal argument is an exact fit for the situation. –CPerkins Oct 1 '09 at 15:10 add a comment| up vote 9 down vote I've IllegalArgumentException: A method was passed an invalid or inappropriate argument or invoked on an inappropriate object. The StackOverflowError error is thrown by the JVM when a Java program calls itself so many times that the memory stack allocated to execute the Java program "overflows." * NoClassDefFoundError is Runtimeexception Java 8 ClassCastException This exception is thrown when there is an attempt to cast a reference to an object to an inappropriate type.
InstantiationException: An attempt was made to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated because it is an ClassCastException: An attempt has been made to cast (§5.4, §15.15) a reference to an object to an inappropriate type. java.lang.LinkageError extends java.lang.Error. for example: if a negative subscript is used or a subscript k where k≥NIndexOutOfBoundsExceptionsame as ArrayIndexOutOfBounds, however is used on listsIllegalArgumentExceptionthrown to indicate a method has passed an illegal or inappropriate
A Java program should not try to handle the standard error classes. Runtimeexception Vs Exception for example: when you divide by zeroNullPointerExceptionthrown when you attempt to call null on an operation where an object is required. includes: Calling instance of null object, Accessing or modifying the field of a null object, Taking the length of a null object.ClassCastExceptionrun-time exception thrown to signal an attempt to cast an A NullPointerException can occur anywhere a program tries to dereference a reference to an object.
IllegalMonitorStateException: A thread has attempted to wait on (§20.1.6, §20.1.7, §20.1.8) or notify (§20.1.9, §20.1.10) other threads waiting on an object that it has not locked. The negative order integer challenge, but it's Prime Time! Java Runtime Exception Vs Checked Exception Usually this error is caught by the compiler; this error can occur at run-time if the definition of a class is changed after the class that references it was last compiled. Runtime Exception Example Runtime Exceptions The RuntimeException class represents exceptions that occur within the Java virtual machine (during runtime).
The cause is not initialized, and may subsequently be initialized by a call to Throwable.initCause(java.lang.Throwable). http://evollux.net/runtime-exception/when-should-i-throw-a-runtime-exception.html ArrayStoreException Assignment to an array element of an incompatible type. SecurityException: A security violation was detected (§20.17). Package java.util defines the following additional standard unchecked runtime exceptions: java.util.EmptyStackException: An attempt was made to access an element of an empty stack. share|improve this answer edited Dec 30 '13 at 13:19 Steve Chambers 11.4k105497 answered Oct 1 '09 at 9:26 KLE 16.1k23952 1 Great points man!! –Winston Chen Oct 1 '09 at How To Handle Runtime Exception In Java
System.exit() does not return. IOException, SQLException). checked.unchecked...........................................Runtime..........................................ExceptionAn exception is an object of the class java.lang.Throwable. Source null reference passed in when not expected, array index out of bounds, etc.) while checked exceptions should represent exceptional conditions in the environment that cannot be "coded away" (e.g.
java.util.NoSuchElementException: An attempt was made to access an element of an empty vector. 184.108.40.206 Standard Checked Exceptions The standard subclasses of Exception other than RuntimeException are all checked exception classes. Java.lang.runtimeexception Error In what situations do you use them? You also steal or launder money.
If a method does throw an Error class or any of its subclasses, the method is not required to declare that fact in its throws clause. This error is new in Java 1.1. Throwable has two immediate subclasses: Exception and Error. Throw New Runtimeexception Also see the documentation redistribution policy.
You can use the operator instanceof to verify whether an object can be cast to another class before casting it. * IllegalArgumentException is a runtime exception. This exception is thrown if the file that the code is trying to access can't be found.How can runtime exceptions get masked during initialization?Runtime exceptions arising from any of the following java.io.FileNotFoundException: A file with the name specified by a file name string or path was not found within the file system. have a peek here As you can see from the diagram, Throwable has two direct descendants: Error and Exception.
IllegalArgumentException Illegal argument used to invoke a method. I use IllegalStateException to signal that an object is incorrectly configured or that calls are in an incorrect order. This situation occurs when the current definition of the referenced class is incompatible with the definition of the class that was found when the referring class was compiled. One of the main reasons for the JVM taking the responsibility for throwing this exception itself is that this exception isn't known until runtime and depends on the array or list
The class java.lang.NullPointerException extends java.lang.RuntimeException. Most programs you write will throw and catch Exceptions. Errors which are of the sort that are external to the system and are probably un-recoverable.3. This exception is new in Java 1.1.
java.io.InterruptedIOException: The current thread was waiting for completion of an I/O operation, and another thread has interrupted the current thread, using the interrupt method of class Thread (§20.20.31). IllegalAccessException This exception is thrown when a program tries to dynamically load a class (i.e., uses the forName() method of the Class class, or the findSystemClass() or the loadClass() method of How about you? SecurityException Attempt to violate security.
NoClassDefFoundError is thrown by the JVM or a ClassLoader when it is unable to load the definition of a class required to create an object of the class. Runtime exceptions The java.lang package defines the following standard runtime exception classes: ArithmeticException This exception is thrown to indicate an exceptional arithmetic condition, such as integer division by zero. IllegalAccessError This error is thrown when a class attempts to access a field or call a method it does not have access to. A Java program should try to handle all of the standard exception classes, since they represent routine abnormal conditions that should be anticipated and caught to prevent program termination.
