Last Updated : 06 Feb, 2019

The getMessage() method of Throwable class is used to return a detailed message of the Throwable object which can also be null. One can use this method to get the detail message of exception as a string value. Syntax:

public String getMessage()

Return Value: This method returns the detailed message of this Throwable instance. Below programs demonstrate the getMessage() method of java.lang.Throwable Class Example 1:

Java

// Java program to demonstrate
// the getMessage() Method.

import java.io.*;

class GFG {

    // Main Method
    public static void main(String[] args)
        throws Exception
    {

        try {

            // divide the numbers
            divide(2, 0);
        }

        catch (ArithmeticException e) {

            System.out.println("Message String = "
                               + e.getMessage());
        }
    }

    // method which divide two numbers
    public static void divide(int a, int b)
        throws ArithmeticException
    {

        int c = a / b;

        System.out.println("Result:" + c);
    }
}

Output:

Message String = / by zero

Example 2:

Java

// Java program to demonstrate
// the getMessage() Method.

import java.io.*;

class GFG {

    // Main Method
    public static void main(String[] args)
        throws Exception
    {

        try {

            test();
        }

        catch (Throwable e) {

            System.out.println("Message of Exception : "
                               + e.getMessage());
        }
    }

    // method which throws UnsupportedOperationException
    public static void test()
        throws UnsupportedOperationException
    {

        throw new UnsupportedOperationException();
    }
}
