如何缩短Java / Android中的代码？

Question

有没有办法缩短此声明代码？

boolean installed1 = false;
boolean installed2 = false;
boolean installed3 = false;
boolean installed4 = false;

...等

Answer 1

是。使用数组或ArrayList<Boolean>

boolean installed[] = {false,false,false,false};
//Access it by index i.e installed[0] 

<强> OR

您只想减少代码及其类级别声明，因为boolean的默认值为false

boolean installed1,installed2,installed3,installed4;

如果是本地声明，

boolean installed1,installed2,installed3,installed4;
installed1=installed2=installed3=installed4=false;

Answer 2

这似乎是最短的方式：

boolean installed[] = new boolean[4];
