Please solve this problem.

Question

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?

Answer 1

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);
