Usage

From source file:Main.java

public static void main(String[] args) {

    Date date = new Date();
    Date date2 = new Date();

    // make 3 comparisons with them
    int comparison = date.compareTo(date2);
    int comparison2 = date2.compareTo(date);
    int comparison3 = date.compareTo(date);

    // print the results
    System.out.println("Comparison Result:" + comparison);
    System.out.println("Comparison2 Result:" + comparison2);
    System.out.println("Comparison3 Result:" + comparison3);

}

From source file:Main.java

    int results = d1.compareTo(d2);
    if (results > 0) {
