java - 根据用户输入查找数组中的最大数字

Question

我正在尝试创建一个程序，该程序可以找到整数数组中比用户使用 JOptionPane 输入的最大数字。这是我到目前为止的代码，但在编译时出现错误。

import javaz.swing.JOptionPane;
public class Week9Largest {
public static void main(String[] args) {
int [] x = new int [7] ;
string myString;
int myInt;
    for(int i = 0; i <= 6; i++){
    myString = JOptionPane.showInputDialog (null, "Enter " +  "integer " + (i + 1));
    myInt = Integer.parseInt(myString);
    x[i] = myInt;           
    }
    int largest = Integer.MIN_VALUE;
    for (int i=0;i<numbers.length;i++){
        if(myInt[i]>largest){
            largest = myInt[i];
        }
    }
    System.out.println("Largest number in array is : " +largest);

  }                                 

Answer 1

更正这个:

 string myString;

致:

 String myString;

这是纠正一些问题后的代码，没问题:

 public static void main(String[] args) {
    int[] x = new int[7];
    String myString;
    int myInt;
    for (int i = 0; i <= 6; i++) {
        myString = JOptionPane.showInputDialog(null, "Enter " + "integer "
                + (i + 1));
        myInt = Integer.parseInt(myString);
        x[i] = myInt;
    }
    int largest = Integer.MIN_VALUE;
    for (int i = 0; i < x.length; i++) {
        if (x[i] > largest) {
            largest = x[i];
        }
    }
    System.out.println("Largest number in array is : " + largest);

}

因为你在这个循环中有错误:

   for (int i=0;i<numbers.length;i++){
    if(myInt[i]>largest){
        largest = myInt[i];
    }

修正后变成:

 for (int i = 0; i < x.length; i++) {
    if (x[i] > largest) {
        largest = x[i];
    }
