      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. `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. Since: 1.0 See Also: Serialized Form See The Java™ Language Specification : 11.2 Compile-Time Checking of Exceptions

### constructor:RuntimeException() [NONE]
- #### 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)`.

### constructor:RuntimeException(java.lang.String) [NONE]
- #### 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.

### constructor:RuntimeException(java.lang.String, java.lang.Throwable) [NONE]
- #### 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 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 `Throwable.getMessage()` method). `cause` - the cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) Since: 1.4

### constructor:RuntimeException(java.lang.Throwable) [NONE]
- #### 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 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 `Throwable.getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) Since: 1.4

### constructor:RuntimeException(java.lang.String, java.lang.Throwable, boolean, boolean) [NONE]
- #### RuntimeException
      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 Since: 1.7
