The class `Exception` and any subclasses that are not also subclasses of `RuntimeException` are checked exceptions . Checked exceptions 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. See Java Language Specification : 11.2 Compile-Time Checking of Exceptions Since: 1.0 See Also: `Error` Serialized Form

### constructor:Exception() [NONE]
### Exception public Exception() Constructs a new 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:Exception(java.lang.String) [NONE]
### Exception public Exception (String message) Constructs a new 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:Exception(java.lang.String,java.lang.Throwable) [NONE]
### Exception public Exception (String message, Throwable cause) Constructs a new exception with the specified detail message and cause. Note that the detail message associated with `cause` is not automatically incorporated in this 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:Exception(java.lang.Throwable) [NONE]
### Exception public Exception (Throwable cause) Constructs a new 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 exceptions that are little more than wrappers for other throwables (for example, `PrivilegedActionException`). 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:Exception(java.lang.String,java.lang.Throwable,boolean,boolean) [NONE]
### Exception protected Exception (String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) Constructs a new 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
