The correct answer is: True
Explanation:
Consider the following program:
<span>class Main {
int a = 10;
public static void main(String[] args) {
add();
}
private static void add() {
int b = a+20;
System.out.println(b);
}<span>
}
The output of the above program is 30. As you can see the variable a is declared outside the method, whereas variable b is declared inside the method.</span></span>
