The import java.util.Arrays cannot be resolved

Question

i'm using Ubuntu 16, and started tutorial on java, and now i have one issue with my code, the method "Arrays.toString()", like all path "java.util.Arrays", is not found, and i really do not know, what i need to do.

This is my code:

package introtocs.arrayalgorithms;

import java.util.Arrays; // First issue here

public class FillingAndDeleting {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // Filling Arrays
        int[] oneThroughTen = new int[10];
        for (int i = 0; i < oneThroughTen.length; i++) {
            oneThroughTen[i] = i + 1;
            System.out.println(Arrays.toString(oneThroughTen)); // Second here
        }

    }

}

Please help, i cant continue.

Answer 1

该代码在我的日食上正常运行，我想也许您没有构建路径，所以导入Arrays utils时出错。

Answer 2

解决方案是将文件添加到当前Eclipse项目"util -> Arrays.java" ，制作软件包util，然后从链接下载文件Arrays.java。
