英文:

I cannot use java array.remove() on int[]

问题

以下是翻译好的内容：

我刚接触Java，并且我在一门课程中需要为作业从数组中移除重复元素，但是我在我的代码中遇到了一个障碍：

异常线程"main" java.lang.Error: 未解决的编译问题：
无法在数组类型int[]上调用remove(int)

at File10.main(File10.java:17)

这是我目前的代码：
```java
import java.util.ArrayList;

public class Homework10 {
	public static void main(String[] args) {
		int arrayLength = (int) (Math.random()*50);
		int[] randomArray = new int[arrayLength];
		for (int i =0; i<arrayLength; i++) {
			randomArray[i] = (int) (Math.random()*20);
		}
		System.out.println("原始数组：");
		for (int i =0; i<arrayLength; i++) {
			System.out.print(randomArray[i] + " ");
		}
		for (int i =0; i<randomArray.length; i++) {
			for (int k =(i + 1); k<randomArray.length; k++) {
				if (randomArray[i] == randomArray[k]) {
					randomArray.remove(k);
				}
			}
		}
	}
}

我已经检查过的所有内容要么与我的代码无关，要么证明我的代码中不应该有错误。

I am new to Java, and I am in a class where for the homework, I need to remove duplicate elements in an array, but I have come across an obstacle in my code:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
Cannot invoke remove(int) on the array type int[]

at File10.main(File10.java:17)

This is my code so far:
```java
import java.util.ArrayList;

public class Homework10 {
	public static void main(String[] args) {
		int arrayLength = (int) (Math.random()*50);
		int[] randomArray = new int[arrayLength];
		for (int i =0; i<arrayLength; i++) {
			randomArray[i] = (int) (Math.random()*20);
		}
		System.out.println("Original Array:");
		for (int i =0; i<arrayLength; i++) {
			System.out.print(randomArray[i] + " ");
		}
		for (int i =0; i<randomArray.length; i++) {
			for (int k =(i + 1); k<randomArray.length; k++) {
				if (randomArray[i] == randomArray[k]) {
					randomArray.remove(k);
				}
			}
		}
	}
}

Everything I have checked either does not relate to my code or proves that there shouldn't be an error in my code.

得分: 1

在数组上没有 remove() 方法。请使用 ArrayList，或阅读关于数组的API文档。

英文:

There is no remove() method on an array. Use an ArrayList, or read the api on arrays.
