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”
