Question
Apply what you have learned in Unit 1 about data types, operands, functions, and conditions in simple Java programs to answer the following question:This Java snippet checks whether a number is even or odd. Which method would make the most sense for line 2?1 Scanner input = new Scanner(System.in);2 int age = input.;3 if (age _____ == 0){4 System.out.println("Your age is even.");5 } else {6 System.out.println(__);7 }
Solution
The Java snippet you provided is checking whether a number (in this case, age) is even or odd. Here's how you would fill in the blanks:
- Scanner input = new Scanner(System.in);
- int age = input.nextInt(); // This method reads the next integer from the input.
- if (age % 2 == 0){ // The modulus operator (%) returns the remainder of the division. If the remainder is 0, the number is even.
- System.out.println("Your age is even.");
- } else {
- System.out.println("Your age is odd."); // If the number is not even, it must be odd.
- }
So, the complete code would look like this:
Scanner input = new Scanner(System.in);
int age = input.nextInt();
if (age % 2 == 0){
System.out.println("Your age is even.");
} else {
System.out.println("Your age is odd.");
}

Problem StatementAmil, a curious coder, has a distinctive approach to handling numerical input. Write a program to get an integer from the user. If the number is even, the system employs a goto statement to a label indicating an affirmative response. Otherwise, another goto statement conveys a negative response.Input format :The input consists of a single integer n.Output format :The output displays one of the following:If n is an even number, it displays "You entered an even number."If n is an odd number, it displays "You entered an odd number."Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:1 ≤ n ≤ 100Sample test cases :Input 1 :1Output 1 :You entered an odd number.Input 2 :100Output 2 :You entered an even number.Input 3 :67Output 3 :You entered an odd number.
Single File Programming QuestionProblem StatementManoj wants to explore numbers. The number should be even and also a multiple of 10. Write a program to obtain a number x and check if it is even or not. If even, check whether it is a multiple of 10 or not.Function Specifications:void iseven(int x) - Prints whether the input number is even or not.void ismultiple(int x) - Prints whether the input number is a multiple of 10 or not.Input format :The input consists of an integer x.Output format :The first line displays "Even" if x is even or "Not even" otherwise.If x is even, the second line displays "Multiple of 10" if x is a multiple of 10 or "Not a multiple of 10" otherwise.Refer to the sample output for formatting specifications.Code constraints :In this scenario, the test cases fall under the following constraints:1 ≤ x ≤ 106Sample test cases :Input 1 :50Output 1 :EvenMultiple of 10Input 2 :13Output 2 :Not evenInput 3 :1Output 3 :Not evenInput 4 :1456Output 4 :EvenNot a multiple of 10Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.

Mandy is a software engineer working on a program to analyze two integers based on specific conditions using a logical operator. She needs to determine if both integers are odd or if at least one of them is divisible by 7.Depending on the result, she wants to print different messages. If the condition is met, the program should identify and print the number that is first divisible by 7 or indicate that both numbers are odd.If the condition is not met, the program should print a message indicating the condition was not met along with the input numbers.Input format :The first line of input consists of an integer representing the first input number.The second line consists of an integer representing the second input number.
