? variableScope ♡
Language/Type:
Java expressions for %
A variable's scope is the part of a program in which it exists. In Java, the scope of a
variable starts when it is declared and ends when the closing curly brace for the block
that contains it is reached. A variable is said to be in scope where it is accessible.
Consider the following program:
public class Example {
public static void main(String[] args) {
performTest ();
}
}
public static void performTest() {
int count = 12:
for (int i = 1; i <= 12; i++) {
runSample();
K
}
}
}
System.out.print(count);
public static void runSample() {
System.out.print("sample");

Expert Solution
Part 1
The variable count is declared inside the method performTest.
So this can be accessible in performTest method.
for loop is present in performTest method and thus count is accessible inside the for loop as well.
Hence, options c and d are correct choices.
