Determine the output of the following program.
public class PredictOutput3
{
public static void main(String args[])
{
int a = 2, b = 2, c = 2;
System.out.println("Output 1: " + (a + 2 < b * c));
System.out.println("Output 2: " + (a + 2 < (b * c)));
}
}
Answer
Output
Output 1: false
Output 2: false
Explanation
In the first println statement, the expression is (a + 2 < b * c). b * c is evaluated first as * has higher precedence than + and <. After that a + 2 is evaluated as between + and <, + has higher precedence. Comparison is done in the end. As 4 < 4 is false so false is printed. The case of second println statement is similar.
