Write a program in Java that ask the user to enter their name, year of birth, and salary. The program must display thier name, age, and salary.

In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3() and a RandomNumbers constructor that set the initial values of all the instance variables to 0. Then write the following 2 instance methods:

• setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive).

• getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3"

Ex: If the input is:

15 20

the output may be:

Random values: 17 15 19

where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive).
