编程思想：1，先简单后复杂先打实心矩形-->实心半金字塔-->实心全金字塔-->空心金字塔 for(int i = 1; i <= 5; i++) { for (int k = 1; k <= 5 - i; k++) { System.out.print(" "); } for (int j = 1; j <= 2 * i - 1; j++) {

//Date类package step1;public class Date { private int year,month,day; public Date(){ year=1999; month=9; day=9; } public Date(int year,int month,int day){ this.year=year; this.month=month; .

package step4;import java.util.Scanner;public class Josephus { public static void main(String args[]){ int total,number; Scanner scan=new Scanner(System.in); total=scan.nextInt(); //输入参与游戏的总人数 number=scan.nextInt(); //输入要报的数字 .

1，不能写while(i--)应该为while(i>0)

只写一个Scanner就行。字符串用 sc.next()接收。字符类型不能接收，没有sc.nextChar(),按照字符串处理就行。package chapter2.step7;/********* Begin *********/import java.util.Scanner;public class HelloWorld{ public static void main(String[] args){ System.out.println("请录入嫦娥个人信息："); .

一行中输入两个数，然后求和sc.hasNextInt()-->sc.nextInt()+sc.nextInt()//函数的使用package step3;import java.util.Scanner;public class IO { public static void main(String[] args) { int number1; int number2; int number3; Scanner sc
