如何缩短Java/Android中的代码？

Question

有没有办法缩短这个声明代码？

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

...等等

Answer 1

是的.使用数组 ORArrayList<Boolean>

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

要么

您只想减少代码及其类级别声明,作为booleanis的默认值false

boolean installed1,installed2,installed3,installed4;

如果是本地声明,

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