java - 如何在android中正确声明静态变量？

Question

我进退两难，因为我不知道什么是更好的解决方案。我有一个静态变量。

我想知道声明这些变量的最佳做法是什么。假设我在 myStatic 类中有这样一个变量。

public class myStatic(){

    public static int integer = 0;

    /* get value */
    public int getInteger() {
        return integer;
    }

    /* set value */
    public void setInteger(int nInteger) {
        integer = nInteger;
    }

}

现在我必须增加这个变量或减少。如何正确操作？

1)

myStatic.integer++;

2)

myStatic mystatic = new myStatic();
int integer = mystatic.getInteger();
int nInteger = integer+1;

mystatic.setInteger(iInteger);

使用解决方案 1 还是 2 更好？

Answer 1

我会选择 1，100%，也许只是因为我懒惰，但有点也是因为:

• Don't repeat yourself

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

• Keep it simple, stupid

This principle has been a key, and a huge success in my years of software engineering. A common problem among software engineers and developers today is that they tend to over complicate problems.

• You aren't gonna need it

Principle of extreme programming (XP) that states a programmer should not add functionality until deemed necessary.
