为什么我收到有关Java数组分配的错误?

问题描述

我正在尝试将int常量分配给数组的certian索引.我不断从编译器中获取错误.文章似乎暗示我已经正确地做到了.这是代码:

I am trying to assign int literals to certian indexs of the array. I keep getting errors from the compiler. This article seems to suggest That I have done this correctly. Here is the code:

public class Mytest {
    int[] jim = new int[9];
    jim[0] = 77;
}

编译器错误:

Mytest.java:5: error: ']' expected
    jim[0] = 77;
        ^
Mytest.java:5: error: ';' expected
    jim[0] = 77;
         ^
Mytest.java:5: error: illegal start of type
    jim[0] = 77;
           ^
Mytest.java:5: error: <identifier> expected
    jim[0] = 77;
            ^

先谢谢了.

推荐答案

您需要将分配语句移至有效位置.这可以是方法，构造函数或初始化块.

You need to move your assignment statement to a valid location. This could be a method, a constructor, or an initialization block.

public class Mytest {
    int[] jim = new int[9];
    // Using an initialization block
    {
        jim[0] = 77;
    }
}
