Exception

open class Exception : Throwable
kotlin.Any
   ↳ kotlin.Throwable
   ↳ java.lang.Exception

The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.

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.

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 initCause.

Exception

Added in API level 1

Exception(
    message: String!,
    cause: Throwable!)

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 String!: the detail message (which is saved for later retrieval by the getMessage() method).
cause Throwable!: 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.)

Exception

Added in API level 1
Exception(cause: Throwable!)

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, ).

Parameters
cause Throwable!: 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.)

Parameters
message String!: the detail message.
cause Throwable!: the cause. (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
