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
