Class Overview

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

RuntimeException and its subclasses are unchecked exceptions. Unchecked exceptions do not need to be declared in a method or constructor's throws clause if they can be thrown by the execution of the method or constructor and propagate outside the method or constructor boundary.

Summary

Public Constructors
RuntimeException()
Constructs a new runtime exception with null as its detail message.
RuntimeException(String message)
Constructs a new runtime exception with the specified detail message.
RuntimeException(String message, Throwable cause)
Constructs a new runtime exception with the specified detail message and cause.
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).
Protected Constructors
RuntimeException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace)
Constructs a new runtime exception with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.

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.)

Protected Constructors

protected RuntimeException (String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace)

Constructs a new runtime exception with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.

Parameters
message the detail message.
cause the cause. (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
enableSuppression whether or not suppression is enabled or disabled
writableStackTrace whether or not the stack trace should be writable
