JAVA 调用方法(函数)实现打印矩形

public class test1 {
    public static void main(String[] args){
        printRectangle(3,5);  //调用printRectangle方法实现打印矩形
        printRectangle(2,4);  
        printRectangle(6,10);
    }
    public static void printRectangle(int height,int width){ 
        for (int i=0;i<height;i++){   //方法就是一段可以重复调用的代码
            for (int j=0;j<width;j++){
                System.out.print("*");
            }
            System.out.println();
        }
        System.out.println();
    }
}

public class test1 {
    public static void main(String[] args) {
        int area = getArea(3, 5);
        System.out.println("The area is " + area);
    }
    public static int getArea(int height,int width) {
        int area = height * width;
        return area;
    }
}
