Java 数组中的最小值和最大值 [英] Java Minimum and Maximum values in Array
本文介绍了Java 数组中的最小值和最大值的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的代码没有给出错误,但是它没有显示最小值和最大值.代码是:
My code does not give errors, however it is not displaying the minimum and maximum values. The code is:
Scanner input = new Scanner(System.in);
int array[] = new int[10];
System.out.println("Enter the numbers now.");
for (int i = 0; i < array.length; i++) {
int next = input.nextInt();
// sentineil that will stop loop when 999 is entered
if (next == 999) {
break;
}
array[i] = next;
// get biggest number
getMaxValue(array);
// get smallest number
getMinValue(array);
}
System.out.println("These are the numbers you have entered.");
printArray(array);
// getting the maximum value
public static int getMaxValue(int[] array) {
int maxValue = array[0];
for (int i = 1; i < array.length; i++) {
if (array[i] > maxValue) {
maxValue = array[i];
}
}
return maxValue;
}
// getting the miniumum value
public static int getMinValue(int[] array) {
int minValue = array[0];
for (int i = 1; i < array.length; i++) {
if (array[i] < minValue) {
minValue = array[i];
}
}
return minValue;
}
//this method prints the elements in an array......
//if this case is true, then that's enough to prove to you that the user input has //been stored in an array!!!!!!!
public static void printArray(int arr[]) {
int n = arr.length;
for (int i = 0; i < n; i++) {
System.out.print(arr[i] + " ");
}
}
我需要一个 system.out.println() 来显示它,还是应该返回工作?
Do I need a system.out.println() to display it, or should the return work?
推荐答案
getMaxValue(array);
// get smallest number
getMinValue(array);
您正在调用方法但未使用返回值.
You are calling the methods but not using the returned values.
System.out.println(getMaxValue(array));
System.out.println(getMinValue(array));
