Integer class byteValue() method
- byteValue() method is available in java.lang package.
- byteValue() method is used to return the value denoted by this Integer object converted to type byte (by casting).
- byteValue() method is a non-static method, it is accessible with class object only and if we try to access the method with the class name then we will get an error.
- byteValue() method does not throw an exception at the time of conversion from Integer to byte.
Syntax
public byte byteValue();
Parameters
- It does not accept any parameter.
Return Value
The return type of this method is byte, it returns a converted (from type Integer to byte) value represented by this Integer object.
Example
// Java program to demonstrate the example
// of byteValue() method of Integer class
public class ByteValueOfIntegerClass {
public static void main(String[] args) {
// Variables initialization
int i1 = 10;
int i2 = 20;
// It returns integer value denoted by this Integer value1 object
// and converted to a byte by calling value1.byteValue()
Integer value1 = new Integer(i1);
// Display value1 result
System.out.println("value1.byteValue(): " + value1.byteValue());
// It returns integer value denoted by this Integer value2 object
// and converted to a byte by calling value2.byteValue()
Integer value2 = new Integer(i2);
// Display value2 result
System.out.println("value2.byteValue(): " + value2.byteValue());
}
}
Output
value1.byteValue(): 10
value2.byteValue(): 20
