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.

Field Summary

Fields inherited from java.lang.Exception:
serialVersionUID

Constructor:

Constructor:
public RuntimeException() { super(); } 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 .
public RuntimeException(String message) { super(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 . Parameters: `message` - the detail message. The detail message is saved for later retrieval by the #getMessage() method.
public RuntimeException(Throwable cause) { super(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.) since: `1.4` -
public RuntimeException(String message, Throwable cause) { super(message, 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.) since: `1.4` -

 public RuntimeException() {
                                     
        super();
}

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

 public RuntimeException(String message) {
        super(message);
}

#initCause

Parameters:

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

 public RuntimeException(Throwable cause) {
        super(cause);
}

(cause==null ? null : cause.toString())

cause

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.)

since: 1.4 -

 public RuntimeException(String message,
    Throwable cause) {
        super(message, 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.)

since: 1.4 -
