问题描述
我试图从我的 int 数组中返回两个最大的整数.我能够返回最大和最小的罚款,但我无法让我的算法返回最大的两个.在这里非常感谢任何帮助.
I am attempting to return the two largest integers from my int array. I am able to return the largest and the smallest fine, but I cannot get my algorithm to return the two largest. Any help is greatly appreciated here.
请原谅我的代码中的任何错误.本期为练习题,题目取自去年大学考试材料.
Please forgive any errors in my code. This is a practice session and the question has been taken from last years exam material at university.
这是我的代码:
public class TwoLargestIntsArray {
public static void main(String [] args){
int [] values = new int[5];
values[0] = 5;
values[1] = 10;
values[2] = 15;
values[3] = 20;
values[4] = 25;
System.out.println(twoLargest(values));
System.out.println();
}
public static int twoLargest(int values[]){
int largestA = values[0];
int largestB = values[0];
for(int i = 0; i < values.length; i++){
if(values[i] > largestA){
largestA = values[i];
}
if(values[i] < largestA){
largestB = values[i];
}
}
return largestA + largestB;
}
}
推荐答案
可以写
public static int[] twoLargest(int values[]){
int largestA = Integer.MIN_VALUE, largestB = Integer.MIN_VALUE;
for(int value : values) {
if(value > largestA) {
largestB = largestA;
largestA = value;
} else if (value > largestB) {
largestB = value;
}
}
return new int[] { largestA, largestB };
}
