package njtcstudent.com;
    
    import java.util.Scanner;
    
    public class Seond {
    
    	public static void main(String[] args) {
    		 findMax();//给定一组字符，编程输出里面数值最大者
    		reverseOrder();//对数组中每一个元素赋值后，按逆序输出
    		maxToMinOrder();//对给定一整型数组，按从大到小顺序输出
    		printInt();//给定一个字符串，编程输出里面所包含的数字
    		whatNumber();//1000以内的水仙花数
    	}
    
    	public static void whatNumber() {
    		int ge,shi,bai;
    		int i;
    		for(i=100;i<1000;i++){
    			bai=i/100;
    			shi= i%100/10;
    			ge=i%100%10;
    			if((Math.pow(bai, 3)+Math.pow(shi, 3)+Math.pow(ge, 3))==i)
    				System.out.println(i);
    		}
    	}
    
    	public static void printInt() {
    		 String strThree = "sdf92r2t4h423rj23r2fj23";
    		 int len = strThree.length();
    		 for(int i=0 ;i<len;i++){
    			 if(strThree.charAt(i)>='0'&&strThree.charAt(i)<='9')
    				 System.out.println(strThree.charAt(i));
    		 }
    	}
    
    	public static void maxToMinOrder() {

    		}
    	}
    
    	public static void findMax() {
    		Scanner inputOne = new Scanner(System.in);
    		System.out.print("请输入一个字符：");
    		String strlone;
    		strlone = inputOne.next();
    		int max=strlone.charAt(0);

    				max=strlone.charAt(i);
    		}
    		System.out.println("The max value is:"+(char)max);
    	}
    
    }

2、3班的这个。

4班的第二个实验报告，只做了第四个，我写的如下：

package com.njtcstudent.javademo;
    
    import java.util.Scanner;
    
    public class wuliantwo {
    
    	public static void main(String[] args) {
    		first();//选择分支结构那个
    		second();//循环结构那个
    
    }
    	private static void second() {
    		int i,s=1;
    		for(i=10;i>=1;i--)
    		{
    			s=s*i;
    			System.out.println(i);
    		}
    		System.out.println("10！的值为："+s);
    	}
    	private static void first(){
    		Scanner myIn = new Scanner(System.in);
    		System.out.println("请输入一个成绩（百分制）：");
    		int gread;
    		gread = myIn.nextInt();
    		if(gread>=0 && gread<=100){
    			gread=gread%10;
    			
    			switch(gread){
    			case 10:case 9:
    				System.out.println("A");
    				break;
    			case 8:
    				System.out.println("B");
    				break;
    			case 7:
    				System.out.println("C");
    				break;
    			default:
    				System.out.println("E");
    				
    			}
    		}
    		else
    			System.out.println("您输入的成绩有误！");
    	}
    	
    }
