jAvA编程题目这个怎么弄啊。不会啊求解答

Java程序: import java.util.Scanner;public class Main{ public static void main(String[] args) { Scanner scan = new Scanner(System.in); int row = 3; int col = 4; double[][] n = new double[row][col]; int i, j; System.out.printf("Enter a %d-by-%d matrix

(1)import java.util.Scanner;public class Test { public static void main(String[] args) { Scanner s = new Scanner(System.in); System.out.println("Please enter"); String name = s.next(); String studentId = s.next(); String specialty = s.next(); System.

double x = reader .nextDouble(); 之后加写:if(x>100 || x<0) throw new IllegalArgumentException("x="+x);

import java.util.Scanner;/** * 1、计算3、6、9的阶乘并输出结果. * */public class Factorial { public int getFact(int n){//阶乘的数 int m = 1; for(int i = 1; i &lt;= n; i++){//从1开始计算到n,也就是1*2*3*n m = m*i; } return m; } public static void main(

class Student {private String name;private int id;private String school;private String department;private int classes;private String birthday;private int startYear;private int dormitory;private String sex;private String phoneNum;private long qqNum;

这个用面向对象 应该很简单的 就是设计一个方法 然后输入不同的值就是了package cn.Majunyi;public class zhidao {/** * @param args */public static double pow(double x,double y){return Math.pow(x, y);} public static void main(String[] args){ double

这个问题不难吧,学程序要勤动手package test;class BankAccount { private String m_sName; private double m_dBalance; private double m_dInterestRate; //private BankAccount b; B

就两个骰子,1-6小,8-12大,还有个7.开始你有100块钱,下注多少押大小中.你输光或他输光就结束!

你的问题是哪个?这么多问题而且还不明确

代码如下: public class App { public static void main(String[] args) { // 手机价格 int prices[] = { 2800, 2900, 2750, 3100 }; int min = prices[0]; for (int i = 1; i < prices.length; i++) { if (min > prices[i]) { min = prices[i]; } } System.out.println("最低价格:" + min); }}运行结果: 2750
