使用Math.random生成随机数

public class Main {

 

  public static void main(String[] args) {/*时 代 J a v a - N o w J a v a . c o m 提 供*/

   

    /*

     * This method returns a positive double value greater than 0.0

     * and less than 1.0

    */

   

    System.out.println("Random numbers between 0.0 and 1.0 are,");

    for(int i=0; i < 5 ; i++)

      System.out.println("Random Number ["+ (i+1) + "] : " + Math.random());

     

    /*

     * To generate random number between 1 to 100 use following code

     */

 

    System.out.println("Random numbers between 1 and 100 are,");

    for(int i=0; i < 5 ; i++)
