public class Pattern3
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
//Taking rows value from the user
System.out.println("How many rows you want in this pattern?");
int rows = sc.nextInt();
System.out.println("Here is your pattern....!!!");
//Printing upper half of the pattern
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j <= i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
//Printing lower half of the pattern
for (int i = rows-1; i >= 1; i--)
{
for (int j = 1; j <= i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
//Closing the resources
sc.close();
}
}

- How to convert Decimal to Hexadecimal in Java?
Java Program to convert Decimal values to Hexadecimal values :
import java.util.Scanner;
public class DecimalToHexadecimal {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter decimal number you like: ");
int deci = input.nextInt();
System.out.println("The hexadecimal number for decimal "
+ deci + " is " + convert(deci));
}
public static String convert(int decimal) {
String hex = "";
while (decimal != 0) {
int hexValue = decimal % 16;
hex = toHexadecimal(hexValue) + hex;
decimal = decimal / 16;
}
return hex;
}
public static char toHexadecimal(int hexValue) {
if (hexValue <= 9 && hexValue >= 0) {
return (char) (hexValue + '0');
} else {
return (char) (hexValue - 10 + 'A');
}
}
}
Output :
Enter decimal number you like: 1234
The hexadecimal number for decimal 1234 is 4D2
