Question

我正在尝试制作一个要求多个输入的脚本，然后将它们打印出来。

例如：

您想要多少输入？ - ＆GT; 3
1.输入是什么？ - ＆GT; 5
什么是2.输入？ - ＆GT; 3
3.输入是什么？ - ＆GT; 4

您提供了以下输入：

1）5
2）3
3）4

下面你可以看到我有多远。很好地询问所有输入，但我无法弄清楚如何在输入下面打印它们。

import java.util.Scanner;

public class Inputs {
    public static void main(String[] args){
        Scanner read = new Scanner(System.in);

        System.out.println("How many inputs?");
        int inp=read.nextInt();


        for (int i=1;i<=inp;i++){
            System.out.print("What was " + i + ". input? ");
            int print=read.nextInt();
            System.out.println(print);
        }

    }
}

Answer 1

public class Inputs {
    public static void main(String[] args){
        Scanner read = new Scanner(System.in);

    System.out.println("How many inputs?");
    int inp=read.nextInt();
    int[] answers = new int[inp];

    for (int i=1;i<=inp;i++){
        System.out.print("What was " + i + ". input? ");
        int print=read.nextInt();
        System.out.println(print);

        answers[i] = print;
    }
    int index = 0;
    for(int a : answers){
        System.out.println( index + ")" + " " + a);
        index ++;
    }
 }
}

你可以自己编码清理它作为一种做法=）

Answer 2

您可以使用集合（我使用列表）来保护您的输入;

public class Inputs {
   public static void main(String[] args){
    Scanner read = new Scanner(System.in);

    System.out.println("How many inputs?");
    int inp=read.nextInt();

    List<Integer> numbers = new ArrayList<Integer>();
    for (int i=1;i<=inp;i++){
        System.out.print("What was " + i + ". input? ");
        int print=read.nextInt();
        numbers.add(print);
        System.out.println(print);
    }
    System.out.println("Inputs are :");
    for (Integer integer : numbers) {
        System.out.println(integer);
    }
 }
}

输出是;

How many inputs?
3
What was 1. input? 5
5
What was 2. input? 3
3
What was 3. input? 4
4
Inputs are :
5
3
4

Answer 3

您需要创建一个整数数组供以后使用。

int array = new int[inp];

Answer 4

您需要存储输入并稍后打印

import java.util.Scanner;

public class Inputs {
public static void main(String[] args){
    Scanner read = new Scanner(System.in);

    System.out.println("How many inputs?");
    int inp=read.nextInt();
    int[] keepInputsHere=new int[inp];


    for (int i=0;i<inp;i++){
        System.out.print("What was " + i + ". input? ");
        int readInt=read.nextInt();
        keepInputsHere[i]=readInt;
    }
     System.out.print("Print results: ");
     for (int i=0;i<inp;i++){
        System.out.print( keepInputsHere[i]);         
     }

}
}

别忘了关闭扫描仪并将登录信息分成不同的功能：

public class Inputs {
        public static void main(String[] args) {

            Scanner read = new Scanner(System.in);
            System.out.println("How many inputs?");
            int inp = read.nextInt();
            Print(ReadInput(inp,read));
        }

        private static int[] ReadInput(int questionsNo, Scanner sc) {
            int[] inputs = new int[questionsNo];

            for (int i = 0; i < questionsNo; i++) {
                System.out.print("What was " + i + ". input? ");
                int readInt = sc.nextInt();
                inputs[i] = readInt;
            }
            sc.close();
            return inputs;
        }

        private static void Print(int[] inputs) {
            System.out.println("Print results: ");
            for (int i = 0; i < inputs.length; i++) {
                System.out.println( i + ")" + " " + inputs[i]);
            }
        }
    }
