Java program converts string to byte array

This is our string.

String str = "Asia is a continent!";

Now, let's use the byte array andgetBytes()Method to achieve our purpose.

byte[] byteVal = str.getBytes();

Now, if we want to get the length of an array, it will return the length, as shown in the complete example below:

Example

public class Demo {
　　　public static void main(String args[]) {
　　　　　　String str = "Asia is a continent!";
　　　　　　System.out.println(str);
　　　　　　//Convert to byte array
　　　　　　byte[] byteVal = str.getBytes();
　　　　　　//Get Length
　　　　　　System.out.println(byteVal.length);
　　　}
}

Output Result

Asia is a continent!
