Answer:
import java.util.Scanner;
public class KboatPattern
{
public void choosePattern() {
Scanner in = new Scanner(System.in);
System.out.println("Type 1 for a triangle");
System.out.println("Type 2 for an inverted triangle");
System.out.print("Enter your choice: ");
int ch = in.nextInt();
System.out.print("Enter the number of terms:
int n = in.nextInt();
switch (ch) {
case 1:
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(i + " ");
System.out.println();
break;
case 2:
for (int i = n; i > 0; i--) {
for (int j = 1; j <= i; j++) {
System.out.print(i + " ");
System.out.println();
break;
default:
System.out.println("Incorrect Choice");
