java - 用户在for循环java中输入更大的数字，错误 "bad operand type"

Question

我需要用 Java 创建一个程序:

-要求 10 个不同的数字。

-告诉最大的数字。

我做了什么:

import java.util.Scanner;

public class BiggerValue {
  public static void main (String [] args) {
   Scanner sc = new Scanner(System.in);
   int bigger;
   int[] n = new int[10];
   System.out.print("Please enter " + n.length + " values:");
   for(int i = 0; i < n.length; i++) {
      n[i] = sc.nextInt(); 
    System.out.println(n[i]);
    if(n < n[i]) {
        bigger = num[i];
       }
     } 
      System.out.println("The highest number is " + bigger);
   }
}

我不知道我这样做是否正确。我在编译时遇到错误 < n[i])

Bad operand types for binary operator '<'
first type:int[] second type:int

Answer 1

n 是数组类型，这导致了错误。他们使用以下代码。

import java.util.Scanner;

public class BiggerValue {
  public static void main (String [] args) {
   Scanner sc = new Scanner(System.in);
   int bigger = 0; //you need to initialise this
   int[] n = new int[10];
   System.out.print("Please enter " + n.length + " values:");
   for(int i = 0; i < n.length; i++) {
      n[i] = sc.nextInt(); 
    System.out.println(n[i]);
    if(bigger < n[i]) { //you should compare it with bigger, not n.
        bigger = n[i]; //there is nothing called num[i], it is n[i]
       }
     } 
      System.out.println("The highest number is " + bigger);
   }
}
