Public class Main{ public static void main(String [] args){ String name=WelcomeJava; Runnable r1=() -> System. out. println(name); String name1 = name. toUpperCase(); Runnable r2=() -> System. out. println(name1); r1.run(); } } What is the output of the above program?

Your program should prompt the user for the dimensions of the two squares matrices, making sure that the user input is greater than or equal to 4.[ yes, an example would be a4x4matrix]2.if the above is not met, prompt the user for a new value.3.now generate random integernumbers to fill both matrices.4.display these two matrices on the screen.5.multiply the two matrices and display the result on the scre
