Convert byte to String in Java

In this Java core tutorial, we learn how to convert byte value into String value in Java via different solutions.

Using String.valueOf() method to instantiate String from a byte value

ConvertByteToStringExample1.java

public class ConvertByteToStringExample1 {
    public static void main(String[] args) {
        byte value1 = 12;
        String value2 = String.valueOf(value1);

        System.out.println("byte value: " + value1);
        System.out.println("String value: " + value2);
    }
}

The output is:

byte value: 12
String value: 12

Using Byte.toString() method to convert a byte value into String

ConvertByteToStringExample2.java

public class ConvertByteToStringExample2 {
    public static void main(String[] args) {
        byte value1 = 29;
        String value2 = Byte.toString(value1);

        System.out.println("byte value: " + value1);
        System.out.println("String value: " + value2);
    }
}

The output is:

byte value: 29
String value: 29

Using Byte.toString() method to return String value from a Byte object

ConvertByteToStringExample3.java

public class ConvertByteToStringExample3 {
    public static void main(String[] args) {
        Byte value1 = 14;
        String value2 = value1.toString();

        System.out.println("byte value: " + value1);
        System.out.println("String value: " + value2);
    }
}

The output is:

byte value: 14
String value: 14

Using String.format() method to format a String from a byte value

ConvertByteToStringExample4.java

public class ConvertByteToStringExample4 {
    public static void main(String[] args) {
        byte value1 = 67;
        String value2 = String.format("%d", value1);

        System.out.println("byte value: " + value1);
        System.out.println("String value: " + value2);
    }
}

The output is:

byte value: 67
String value: 67

Using DecimalFormat class to format a byte value into String

ConvertByteToStringExample5.java

import java.text.DecimalFormat;

public class ConvertByteToStringExample5 {
    public static void main(String[] args) {
        byte value1 = 123;
        DecimalFormat decimalFormat = new DecimalFormat("#");
        String value2 = decimalFormat.format(value1);

        System.out.println("byte value: " + value1);
        System.out.println("String value: " + value2);
    }
}

The output is:

byte value: 123
String value: 123

Happy Coding 😊
