Control Statements

Let's test your knowledge on if-else and switch statements in Java with the following problem statements:

1. Write a Java program to check if a given number num is positive, negative, or zero using if-else statements.

2. Create a Java program to determine whether a given year year is a leap year or not using if-else statements.

3. Write a Java program to find the maximum of three numbers a, b, and c using if-else statements.

4. Develop a Java program to check if a given character ch is a vowel or a consonant using if-else statements.

5. Implement a Java program to check if a given number num is even or odd using if-else statements.

6. Write a Java program to determine the grade of a student based on their percentage percentage using if-else statements.

7. Create a Java program to find the largest among three numbers num1, num2, and num3 using if-else statements.

8. Develop a Java program to determine if a given integer number is divisible by both 2 and 3 using if-else statements.

9. Write a Java program to check if a given string str is palindrome or not using if-else statements.
