Syntax:

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 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 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(); }} |
Output:
Message of Exception : null
