英文:
Why eclipse show me error in the line where i have written public static void main(String[] args)
问题
所以为什么 public static void main(String[] args) 我得到了一个错误。我应该怎么做来解决它？
package linkedList;public class HackerRank {public class Solution {// 完成下面的 aVeryBigSum 函数。public long aVeryBigSum(long[] ar) {long a=0;for(int i=0;i<ar.length;i++){a=ar[i]+a;}return a;}public static void main(String[] args) { /// 为什么这行是不正确的Solution s= new Solution();long[] ar= {10000,20000,30000};System.out.println(s.aVeryBigSum(ar));}}}
英文:
So why public static void main(String[] args) I got an error. what can i do to resolve it?
package linkedList;public class HackerRank {public class Solution {// Complete the aVeryBigSum function below.public long aVeryBigSum(long[] ar) {long a=0;for(int i=0;i<ar.length;i++){a=ar[i]+a;}return a;}public static void main(String[] args) { ///why this line is not correctSolution s= new Solution();long[] ar= {10000,20000,30000};System.out.println(s.aVeryBigSum(ar));}}}

以下是您要翻译的内容：
另一种可能的解决方案是，将嵌套的 Solution 类从 HackerRank 类中提取出来，因为我看到您目前没有对它进行任何操作。
public class Solution {// 完成 aVeryBigSum 方法。public long aVeryBigSum(long[] ar) {long a = 0;for (int i = 0; i < ar.length; i++) {a = ar[i] + a;}return a;}public static void main(String[] args) {Solution s = new Solution();long[] ar = { 10000, 20000, 30000 };System.out.println(s.aVeryBigSum(ar));}}
这样可以确保您的静态 main 方法正常工作。
英文:
There is another possible solution, taking the nested Solution class out of the HackerRank class, as I see you are not doing anything with it at the moment.
public class Solution {// Complete the aVeryBigSum function below.public long aVeryBigSum(long[] ar) {long a = 0;for (int i = 0; i < ar.length; i++) {a = ar[i] + a;}return a;}public static void main(String[] args) {Solution s = new Solution();long[] ar = { 10000, 20000, 30000 };System.out.println(s.aVeryBigSum(ar));}}
This makes sure that your static main method works.

你不能在非静态类中访问静态方法。对于这个问题有两种可能的解决方案：
-
- 使 Solution 类为静态
public static class Solution {
public static void main(String[] args) {//...}
}
-
- 从 main 方法中移除 static 关键字
public class Solution {
public void main(String[] args) {//...}
}
英文:
You can't access a static method in a non-static class. There are 2 possible solutions for this problem:
-
- Make Solution static
public static class Solution {
public static void main(String[] args) {//...}
}
-
- Remove the static from the main method
public class Solution {
public void main(String[] args) {//...}
}
