Java - Long byteValue() method



Description

The Java Long byteValue() method returns the value of this Long as a byte.

Declaration

Following is the declaration for java.lang.Long.byteValue() method

public byte byteValue()

Parameters

NA

Return Value

This method returns the numeric value represented by this object after conversion to type byte.

Exception

NA

Example 1

The following example shows the usage of Long byteValue() method to get a byte from an long. We've created a Long variable and assigned it an Long object created using a positive long value. Then using byteValue() method, we're printing the byte from the Long object.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(10L);
 
      // returns the value of Long as a byte
      byte b = obj.byteValue();
      System.out.println("Value of b = " + b);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value of b = 10

Example 2

The following example shows the usage of Long byteValue() method to get a byte from an long. We've created a Long variable and assigned it an Long object created using a negative long value. Then using byteValue() method, we're printing the byte from the Long object.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(-10L);
 
      // returns the value of Long as a byte
      byte b = obj.byteValue();
      System.out.println("Value of b = " + b);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value of b = -10

Example 3

The following example shows the usage of Long byteValue() method to get a byte from an long. We've created a Long variable and assigned it an Long object created using a zero long value. Then using byteValue() method, we're printing the byte from the Long object.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(0L);
 
      // returns the value of Long as a byte
      byte b = obj.byteValue();
      System.out.println("Value of b = " + b);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value of b = 0

Example 4

The following example shows the usage of Long byteValue() method to get a byte from an long. We've created a Long variable and assigned it an Long object created using a negative zero long value. Then using byteValue() method, we're printing the byte from the Long object.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(-0L);
 
      // returns the value of Long as a byte
      byte b = obj.byteValue();
      System.out.println("Value of b = " + b);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value of b = 0
