i have been learning stack , heap , particularly stack lifo approach. does work nested blocks within methods , can used improve performance e.g. public void test() { int = 5; // int j = 5; // j } in example, @ end of method , j freed stack. would following more efficient? (i know simple procedure.....) or effort of freeing more saving on size of stack? public void test() { { int = 5; // } { int j = 5; // j } } this solely example purposes, know refactor etc. interested in happens memory in method.... the stack allocated whole of method call anyway. there are subtle cases adding blocks help, in terms of captured variables - if have 2 lambda expressions, 1 of captures i , 1 of captures j , in first case you'd end synthesized class captures both variables, whereas in second case you'd end 2 classes... @ least in current implementation. without variable capture, it's @ least possible...
