急急急 求大神 Java编程 ,从键盘输入十个同学的3...

代码如下: 你需要了解Arrays这个工具类,Scanner类 public static void tenStudents() { //十个同学3科成绩,总分 int[][] strs = new int[10][4]; int allSumScore = 0; System.out.println("开始录入"+strs.length+"个同学的成绩:"); for(in...

可以使用数组,来存储输入的3个数字,然后排序,得到最大值 也可以直接一边输出一边判断,参考代码如下 import java.util.Scanner;public class Exam {public static void main(String[] args) {int len =3;System.out.println("请输入"+len+"个数字...

使用for循环即可,代码如下: import java.util.Scanner;public class Demo07 {public static void main(String[] args) {System.out.println("请输入你要求和的数:");//提示用户输入Scanner in = new Scanner(System.in);int max = in.nextInt...

public static void main(String[] args) {int k;System.out.print("请输入第一个数:");Scanner str1 = new Scanner(System.in);int max = Integer.parseInt(str1.next());System.out.print("请输入第二个数:");Scanner str2 = new Scanner(Sy...

public static void main(String[] args) { System.out.println("请输入3位的整数"); Scanner in = new Scanner(System.in); int cr = in.nextInt(); int b = cr / 100; int s = cr / 10 %10; int g = cr % 10; System.out.println("倒序:"+g+"...

import java.util.Scanner; public class Demo1 { public static void main(String[] args){ Scanner scanner = new Scanner(System.in); int number = 0; int sum = 0; System.out.println("输入一个数,按回车输入下一个数:"); for(int i=0;i

//1/1+1/2+2/3+3/5+5/8+8/13+13/21+21/34 public static void test(int param){ double a = 1; double b = 1; double sum = 0; double temp = 0; for (int j = 0; j < param; j++) { sum = sum + a/b; if (j == param-1 ){ System.out.println("...

#include struct Student{ int num; char name[20]; float score[3], average;};int main(void){ int i, j; struct Student std[10] = {0}, temp; puts("Please enter information of student : "); for (i = 0; i < 10; ++i) { scanf("%d%s", &...

import java.util.Scanner; public class Triangle { public static void main(String[] args) { int a; int b; int c; System.out.println("请输入三个正整数:"); Scanner in=new Scanner(System.in); a=in.nextInt(); b=in.nextInt(); c=in.n...

public static double getResult(double a, double b, double c){ 楼下的答案放这里 } main 中 Scanner in=new Scanner(System.in); double a=in.nextDouble(); 同理,b和c 然后 getResult(a,b,c) 就会返回结果
