Java - Integer byteValue() method
Description
The Java Integer byteValue() method returns the value of this Integer as a byte.
Declaration
Following is the declaration for java.lang.Integer.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 Integer byteValue() method to get a byte from an integer. We've created a Integer variable and assigned it an Integer object created using a positive int value. Then using byteValue() method, we're printing the byte from the Integer object.
package com.tutorialspoint; public class IntegerDemo { public static void main(String[] args) { Integer obj = new Integer(10); // returns the value of Integer 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 Integer byteValue() method to get a byte from an integer. We've created a Integer variable and assigned it an Integer object created using a negative int value. Then using byteValue() method, we're printing the byte from the Integer object.
package com.tutorialspoint; public class IntegerDemo { public static void main(String[] args) { Integer obj = new Integer(-10); // returns the value of Integer 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 Integer byteValue() method to get a byte from an integer. We've created a Integer variable and assigned it an Integer object created using a zero int value. Then using byteValue() method, we're printing the byte from the Integer object.
package com.tutorialspoint; public class IntegerDemo { public static void main(String[] args) { Integer obj = new Integer(0); // returns the value of Integer 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 Integer byteValue() method to get a byte from an integer. We've created a Integer variable and assigned it an Integer object created using a negative zero int value. Then using byteValue() method, we're printing the byte from the Integer object.
package com.tutorialspoint; public class IntegerDemo { public static void main(String[] args) { Integer obj = new Integer(-0); // returns the value of Integer 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
