Jawaharlal Nehru Technological University Hyderabad B.Tech III JAVA PROGRAMMING Previous Question Paper (August - 2022 - R16)

Type conversion in Java is the process of converting a value from one data type to another. It is categorized into two types: Widening and Narrowing.

Widening Casting (Implicit): This occurs automatically when a smaller data type is converted into a larger data type. It is safe because there is no loss of data.

Narrowing Casting (Explicit): This must be done manually by placing the target type in parentheses in front of the value. It is necessary when converting a larger data type to a smaller one, which may result in data loss.

The following Java program iterates from 1 to 30 and uses an if statement to check for odd numbers by verifying if the remainder is non-zero when divided by 2.

public class OddNumbers {
    public static void main(String[] args) {
        for (int i = 1; i <= 30; i++) {
            if (i % 2 != 0) {
                System.out.print(i + " ");
            }
        }
    }
}
