Usage

From source file:Main.java

public static void main(String[] args) {
    float f1 = 5.5f;
    float f2 = 5.4f;
    int i1 = Float.compare(f1, f2);
    if (i1 > 0) {
        System.out.println(">");
    } else if (i1 < 0) {
        System.out.println("<");
    } else {/*from  w  w w.j a  v a  2s  .c  o  m*/
        System.out.println("=");
    }

    Float fObj1 = new Float("5.5");
    Float fObj2 = new Float("5.4");
    int i2 = fObj1.compareTo(fObj2);
    if (i2 > 0) {
        System.out.println(">");
    } else if (i2 < 0) {
