Class Overview

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.

Public Constructors

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 initCause(Throwable).

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 initCause(Throwable).

Parameters

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

public RuntimeException (String message, Throwable cause)

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

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

Parameters

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

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 of cause). 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 the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)
