Please solve this problem.

I have defined an array in the main function inside a if statement. When I use that array in an if statement inside the main function, it says "symbol not found". Why?

if(true){ int a=1;} System.out.print(a); //error: cannot find symbol //symbol: variable a something like this ? it happens because variable a is limited to the braces{} inside which it gets declared(int a;) you can remove this error by declaring variable a outside the if block: int a; if(true){ a=1;} System.out.print(a);
