Returns the value of this Integer as a float after a widening primitive conversion.

Usage

From source file:Main.java

public static void main(String[] args) {
    Integer integerObject = new Integer("1234567");

    float f = integerObject.floatValue();
    System.out.println("float" + f);

}

From source file:Main.java

public static void main(String[] args) {
    Integer intObj = new Integer("10");
    byte b = intObj.byteValue();
    System.out.println(b);/*  w w  w .j  a v  a 2 s . c o  m*/

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

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

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

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