1.生成随機數
源代碼
package Zuote;
public class SuiJiShu {
public static void main( String args[] )
{
java.util.Random r=new java.util.Random();
for(int i=0;i<1000;i++)
{
System.out.println(r.nextInt(10)+1);
}
}
}
結果截圖

2.以下代碼的特殊之處
public class MethodOverload {
public static void main(String[] args) {
System.out.println("The square of integer 7 is " + square(7));
System.out.println("\nThe square of double 7.5 is " + square(7.5));
public static int square(int x) {
return x * x;
public static double square(double y) {
return y * y;
該代碼特殊在函數的重載,不同類型相同函數名,當實參為int類型時調用int類型的函數,當實參為double類型時調用double類型的函數
