Usage

From source file:Main.java

public static void main(String[] args) {
    double number = Math.random();
    System.out.println("Generated number: " + number);

    number = Math.random() * 10;/*from  ww w.j  av a 2 s  . co  m*/
    System.out.println("Generated number: " + number);

    number = 100 + (Math.random() * 100);
    System.out.println("Generated number: " + number);

    int random = 100 + (int) (Math.random() * 100);
    System.out.println("Generated number: " + random);
}

From source file:Mortgage.java

public static void main(String[] args) {
    double payment = Math.random() * 1000;
    System.out.println("Your payment is ");
    NumberFormat nf = NumberFormat.getCurrencyInstance();
    System.out.println(nf.format(payment));
}

From source file:Main.java

public static void main(String[] args) {

    // get two random double numbers
    double x = Math.random();
    double y = Math.random();

    // print the numbers and print the higher one
    System.out.println("Random number 1:" + x);
    System.out.println("Random number 2:" + y);
    System.out.println("Highest number:" + Math.max(x, y));

}

From source file:Main.java
