In Java you want to write a program that will prompt the user for a nonnegative value n the program will then do as follows in the discussion help please?

Answer 1

// Set up a Scanner class to read from standard input
final Scanner in = new Scanner(System.in);

// Prompt for input and read the next integer
System.out.print("Please enter a positive integer: ");
int n = in.nextInt();

// Since we want to print out n lines, iterate n times
for (; n > 0; --n) {

// On each iteration, print out the numbers [1,n]
for (int i = 1; i <= n; ++i) {
System.out.print(i + " ");

}
System.out.println();

}

// Remember to close open resources when we're done.
in.close();
