Java编译器不会进入我的for循环？

Question

我正在尝试编写一个应用程序,它将使用随机数填充数组.在我尝试在populateArray方法中输入for循环之前,一切似乎都能正常工作.

import java.util.Random;

public class PerformanceTester {

//takes an empty array, but the size must be allocated BEFORE passing 
//to this function. Function takes a pre-allocated array and input size.
public static int[] populateArray(int[] inputArray, int n) {

    //Create the number generator
    Random generator = new Random();

    int length = inputArray.length;
    System.out.println("Inputted array is length: " + length);

    for (int i = 0; i == length; i++) {
        // for debugging purposes: System.out.println("For loop entered.");
        int random = generator.nextInt((2 * n) / 3);
        // for debugging purposes: System.out.println("Adding " + random + " to the array at index " + i);
        inputArray[i] = random;

    }
    return inputArray;
    }

public static void main(String[] args) {

    int[] input;
    input = new int[10];
    int[] outputArray = populateArray(input, 10);
    System.out.print(outputArray[0]);

}
}

如我的输出所示,编译器清楚地输入方法(当在第29行调用时)但似乎在达到for循环时停止所有执行.我100%确定我的循环有正确的初始化和终止操作符,因为长度等于10.

老实说,我很难过,但大多数情况下,我确定这是一个非常简单的答案.我的输出如下:

Inputted array is length: 10
0 //The array is not populated with numbers, so all indexes of the array return zero.

非常感谢任何和所有的帮助.

当然,你的意思是你的循环测试是正确的吗？

for (int i = 0; i < length; i++) {

否则,i == length永远不会是真的(除非length == 0),它永远不会进入循环.

您也可以使用:

for (int i = 0; i != length; i++) {
