How to get byte array from a string object in java?

Some times we have to convert string object into byte array. You can use getBytes() methode to convert string object to byte array.

package com.myjava.string;

public class MyStringBytes {

    public static void main(String a[]){
    
        String str = "core java api";
        byte[] b = str.getBytes();
        System.out.println("String length: "+str.length());
        System.out.println("Byte array length: "+b.length);
    }
}
