The variable "age" of type int has been declared. Write the code required to ask the user to enter the age, store the entered value in the variable "age". If the value entered by the user is zero or negative then output the msg. "invalid age" and repeat the above steps as many times as required till the user enters a value that is more than zero, then output the value to the screen and do not ask the user for input again. Use a do-while loop

can you please write it in java.util.scanner form Write a program that prompts the user to enter a number within the range of 1 through 10. The program should display the Roman numeral version of that number. If the number is outside the range of 1 through 10, the program should display an error message. but use switch statement for the program.

In this lab, you use the flowchart and pseudocode found in the figure below to add code to a partially created Java program. When completed, college admissions officers should be able to use the Java program to determine whether to accept or reject a student, based on his or her test score and class rank. start input testScore, classRank if testScore >= 90 then if classRank >= 25 then output "Accept" else output "Reject" end if else if testScore >= 80 then if classRank >= 50 then output "Accept" else output "Reject " endif else if testScore >= 70 then if classRank >= 75 then output "Accept" else output "Reject" end if else out put "Reject" end if end if end if stop Instructions Study the pseudocode in picture above. Declare the variables testScoreString and classRankString. Write the interactive input statements to retrieve: A student’s test score (testScoreString) A student's class rank (classRankString) Write the statements to convert the string representation...

Given the following code segment, what will be the value of the variable "num5" after executing the 7th statement? If an error occurs, indicate "error"

Symbolize the following argument and then determine if it is valid or invalid. Everything is physical. Therefore, it is not the case that there is something which isn’t physical.

Can you help me to do this Java program please? Thank you!

Evaluate the following expressions, assume the following declarations: int x = 4 /3 * 2; int y = 9/ 2; int num = 6; num *= x + y; What is the value of the num after expression is evaluated?

Ask the user to enter 2 integers the second one being non-zero. Store these 2 values in int objects named a and b respectively. Use if/else selection statement to do the following: In the case the b is not zero: • compute the integer quotient of a/b and integer remainder a%b store them into q and r. • output these values. In the case that b is zero: • output the message "Division by zero is undefined!" Sample output 1: Enter 2 integers (the second being non-zero): 15 6 15 / 6 2 %3D r 15 % 6 3 Sample output 2: Enter 2 integers (the second being non-zero): 15 0 Division by zero is undefined!

Assume that grade is a variable whose value is a letter student_grade-- any one of the following letters: 'A', 'B', 'C', 'D', 'F". Assume further that there are the following int variables, declared and already initialized: acount, bcount, ccount, dcount, fcount. Write a switch statement that increments the appropriate variable (acount, bcount, ccount, etc.) depending on the value of grade. So if grade is 'A' then acount is incremented; if grade is'B' then bcount is incremented, and so on.
