第一周作业

1.输出学号班级和姓名

public class test1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println("193230516,1905,潘*");
               
    }

2.输出以下图形

     *
    ***
   *****
    ***
     *

public class test1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println("  *  ");
        System.out.println(" *** ");
        System.out.println("*****");
        System.out.println(" *** ");
        System.out.println("  *  ");
               
    }

}

3.定义两个整型变量a=5  b=8  求平方和并输出

public class test1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int a=5;
        int b=8;
        System.out.println(a*a+b*b);
                
    }

}
