Pattern 3 :

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1

 

Java Code for above pattern :


import java.util.Scanner;

 

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();

}

}

Output :

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2

Pattern 2 :

1
2 2
3 3 3
4 4 4 4
5 5 5 5 5

Java Program for the above pattern:


import java.util.Scanner;



public class MainClass

{

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....!!!");



for (int i = 1; i <= rows; i++)

{

for (int j = 1; j <= i; j++)

{

System.out.print(i+" ");

}



System.out.println();

}



//Close the resources
sc.close();

}

}

Q. Write a Java program to print given pattern.

Pattern 1 :

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7

 

Java Program:


import java.util.Scanner;

public class MainClass

{

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....!!!");

for (int i = 1; i <= rows; i++)

{

for (int j = 1; j <= i; j++)

{

System.out.print(j+" ");

}

System.out.println();

}

//Close the resources

sc.close();

}

}
