public class RuntimeException

extends Exception

RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.

A method is not required to declare in its throws clause any subclasses of RuntimeException that might be thrown during the execution of the method but not caught.

JDK1.0

RuntimeException

public RuntimeException()

Constructs a new runtime exception with null as its detail message. The cause is not initialized, and may subsequently be initialized by a call to Throwable.initCause(java.lang.Throwable).

RuntimeException

public RuntimeException(String message)

Constructs a new runtime exception with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to Throwable.initCause(java.lang.Throwable).

Parameters:

message - the detail message. The detail message is saved for later retrieval by the Throwable.getMessage() method.

RuntimeException

public RuntimeException(String message, Throwable cause)

Constructs a new runtime exception with the specified detail message and cause.

Note that the detail message associated withcause is not automatically incorporated in this runtime exception's detail message.

Parameters:

message - the detail message (which is saved for later retrieval by the Throwable.getMessage() method).

cause - the cause (which is saved for later retrieval by theThrowable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Since:

1.4

RuntimeException

public RuntimeException(Throwable cause)

Constructs a new runtime exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message ofcause). This constructor is useful for runtime exceptions that are little more than wrappers for other throwables.

Parameters:

cause - the cause (which is saved for later retrieval by theThrowable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Since:

1.4
