Java String getBytes() Example 1

public class JavaStringGetBytesEx1
{ 
                     public static void main(String args[])
{ 
            String s1="ghijklm"; 
            byte[] barr=s1.getBytes(); 
            for(int i=0;i<barr.length;i++){ 
             System.out.println(barr[i]); 
     } 
   }
}

Output:

103
104
105
106
107
108

Java String getBytes() Example 2

public class JavaStringGetBytesEx2
{
    public static void main(String[] args)
    {
        String str = "tutorialandexample";
        // Copy the contents of the String to a byte array.
byte[] byte_arr = str.getBytes();
        // Create a new String using the contents of the byte array.
        String new_str = new String(byte_arr);
        String str1 = new_str.concat(".com");
        // Display the contents of the byte array.
System.out.println("\nBest online Tutorial site : " +
str1 + "\n");
    }
}

Output:

Best online Tutorial site : tutorialandexample.com

Java String getBytes() Example 3

import java.nio.charset.Charset;
public class JavaStringGetBytesEx3 {
  public static void main(String[] args) {
    try {
      String str = "tutorialandexample.com";
      System.out.println();
      System.out.println("\n Given String = " + str);
      // copy the contents of the String to a byte array
      byte[] arr = str.getBytes(Charset.forName("ASCII"));
      String s1 = new String(arr);
      System.out.println(" New string = " + s1);
            System.out.println();
    } catch (Exception e) {
      System.out.print(e.toString());
      System.out.println();
    }
  }
}

Output:

Given String = tutorialandexample.com
New string = tutorialandexample.com

Java String getBytes() Example 4

import java.nio.charset.Charset;
public class JavaStringGetBytesEx4 {
  public static void main(String[] args) {
    try {
      String str = "tutorialandexample.com";
      System.out.println();
      System.out.println("\n Given String = " + str);
      // copy the contents of the String to a byte array
      byte[] arr = str.getBytes(Charset.forName("ASCII"));
       for(int i=0;i<arr.length;i++){ 
            System.out.println(arr[i]); 
        }
      String s1 = new String(arr);
      System.out.println(" New string = " + s1);
            System.out.println();
    } catch (Exception e) {
      System.out.print(e.toString());
      System.out.println();
    }
  }
}

Output:

Given String = tutorialandexample.com
