Throwable Throwable(String, Throwable) in Java

Throwable(String, Throwable): This method is available in the java.lang.Throwable class of Java.

Syntax:

java.lang.Throwable.Throwable(String message, Throwable cause)

This method takes two arguments. This method constructs a new throwable with the specified detail message and cause.

Note that the detailed message associated with the cause is not automatically incorporated in this throwable's detail message.

Parameters: Two parameters are required for this method.

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

cause: the cause (saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Exceptions: NA

Approach

Java

public class Throwable4 {
    public static void main(String[] args) {

        String message = "Hello";
        Throwable cause = new NullPointerException();
        Throwable throwable = new Throwable(message, cause);

        System.out.println(throwable);
    }
}

Output:

java.lang.Throwable: Hello
