可以通过”Scanner“函数 直接输入参数的形式，来实现输入语句，举例：

import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
System.out.println("请输入一个整数：");
int length=input.nextInt();//输入一个整数
System.out.println("输入的整数是："+length);}
}
备注：Scanner函数就是用来进行语句输入的，上面举例的是整数类型，也可以用以下语句“String length=input.next()”，输入的就是字符串类型等。
import java.util.Scanner;
/**

public class Ceshi {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请依次输入1-10的数字");
for(int i=1;i11;i++){
int ceshi = scanner.nextInt();
switch (ceshi) {
case 1:
System.out.println("1对应的字母是A");
break;
case 2:
System.out.println("2对应的字母是B");
break;
case 3:
System.out.println("3对应的字母是C");
break;
case 4:
System.out.println("4对应的字母是D");
break;
case 5:
System.out.println("5对应的字母是E");
break;
case 6:
System.out.println("6对应的字母是F");
break;
case 7:
System.out.println("7对应的字母是G");
break;
case 8:
System.out.println("8对应的字母是H");
break;
case 9:
System.out.println("9对应的字母是I");
break;
case 10:
System.out.println("10对应的字母是J");
break;
default:
break;
}
}
}
}
结果为：
