7.21 LAB: Random values use Java. 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(). 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). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range. import java.util.Scanner; public class LabProgram {// main method used to test your codepublic…

Complete main() to: create a generic pet and print information using PrintInfo(). create a Cat pet, use PrintInfo() to print information, and add a statement to print the cat's breed using the GetBreed() function. Ex. If the input is: Dobby 2 Kreacher 3 Scottish Fold the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: Scottish Fold
