The java.lang.Float.byteValue() is a built-in method in Java that returns the value of this Float as a byte(by casting to a byte). Basically it used for narrowing primitive conversion of Float type to a byte value.
Syntax:
public byte byteValue()
Parameters: The function does not accept any parameter.
Return Value: This method returns the Float value represented by this object converted to type byte.
Examples:
Input : 12 Output : 12 Input : 1023 Output : -1
Below programs illustrates the java.lang.Float.byteValue() function:
Program 1:
// Program to illustrate the Float.byteValue() methodimport java.lang.*;  public class GFG {      public static void main(String[] args)    {          Float value = 1023f;          // Returns the value of Float as a byte        byte byteValue = value.byteValue();        System.out.println("Byte Value of num = " + byteValue);          // Another example        value = 12f;        byteValue = value.byteValue();        System.out.println("Byte Value of num = " + byteValue);    }} |
Output:
Byte Value of num = -1 Byte Value of num = 12
Program 2 : Demonstrates the byte value for a negative number.
// Java code to illustrate java.lang.Float.byteValue() methodimport java.lang.*;  public class GFG {      public static void main(String[] args)    {          Float value = -1023f;          // Returns the value of Float as a byte        byte byteValue = value.byteValue();        System.out.println("Byte Value of num = " + byteValue);          // Another example        value = -12f;        byteValue = value.byteValue();        System.out.println("Byte Value of num = " + byteValue);    }} |
Output:
Byte Value of num = 1 Byte Value of num = -12
Program 3 : When a decimal value is passed in argument.
// Program to illustrate java.lang.Float.byteValue() method  import java.lang.*;  public class GFG {      public static void main(String[] args)    {          Float value = 11.24f;          // Returns the value of Float as a byte        byte byteValue = value.byteValue();        System.out.println("Byte Value of num = " + byteValue);          // Another example        value = 6.0f;        byteValue = value.byteValue();        System.out.println("Byte Value of num = " + byteValue);    }} |
Output:
Byte Value of num = 11 Byte Value of num = 6
