Returns the value of this Float as a byte after a narrowing primitive conversion.

Usage

From source file:Main.java

    Float floatObject = new Float("10.01");
    byte b = floatObject.byteValue();
    System.out.println("byte:" + b);

}

From source file:Main.java

public static void main(String[] args) {

    Float fObj = new Float("10.50");
    byte b = fObj.byteValue();
    System.out.println(b);//from w  w w . j  av  a2s .  c o m

    short s = fObj.shortValue();
    System.out.println(s);

    int i = fObj.intValue();
    System.out.println(i);

    float f = fObj.floatValue();
    System.out.println(f);

    double d = fObj.doubleValue();
    System.out.println(d);
