Java program to create combined Pyramid pattern using while loop

In this tutorial, we will discuss a concept of the Java program to create Combined Pyramid pattern

In the Java programming language, we can use for loop ,while loop and do-while loop to display different number (binary, decimal), alphabets or star pattern programs.

In this article, we are going to learn how to Display combined Pyramid pattern using while loop in Java language

Program to display combined Pyramid star pattern

Combined Pyramid star pattern 1

Program 1

The Java program allows the user to enter the number of rows then it displays two combined straight pyramid star pattern according to the number of rows.

import java.util.Scanner;
class JointedPyramidwhile1{
public static void main(String args[]){
    int i,j;  //variable declaration
    Scanner scan=new Scanner(System.in);
//create a scanner object for input

//get input from the user for rows
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();
System.out.print("\n");

i=1; 
while(i<=rows){  //parent while loop
    j=i; 
  while(j<=rows){
  System.out.print(" ");//print space
  j++;
  }
  j=1;
  while( j<=2*i-1){
  System.out.print("*");//print star
   j++;
  }
  j=2*i; 
   while(j<=2*rows-1){
  System.out.print(" ");//print space
  j++;
   }
   j=1;
  while( j<=2*i-1){
  System.out.print("*");//print star
  j++;
  }
  System.out.print("\n");//move to next line
i++;
}

}


}

When the above code is executed, it produces the following results

Program 2

The Java program allows the user to enter the number of rows then it displays two combined upside-down pyramid star pattern according to the number of rows.

import java.util.Scanner;
class JointedPyramidwhile2{
public static void main(String args[]){
    int i,j;  //variable declaration
    Scanner scan=new Scanner(System.in);
//create a scanner object for input

//get input from the user for rows
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();
System.out.print("\n");
i=1;
while( i<=rows){//parent while loop
	j=1; 
  while(j<i){
  System.out.print(" ");//print space
   j++;
  }
  j=1; 
  while(j<2*(rows-i+1)){
  System.out.print("*");//print star
   j++;
  }
  j=2; 
   while(j<2*i){
  System.out.print(" ");//print space
  j++;
   }
   j=1;
  while( j<2*(rows-i+1)){
  System.out.print("*");//print star
   j++;
  }
  System.out.print("\n");
   i++;

}

}


}

When the above code is executed, it produces the following results

Java program to print combined Pyramid number pattern

Combined Pyramid number pattern 1

Program 1

The Java program allows the user to enter the number of rows then it displays two combined straight pyramid number pattern according to the number of rows.

import java.util.Scanner;
class JointedPyramidwhile1{
public static void main(String args[]){
    int i,j;  //variable declaration
    Scanner scan=new Scanner(System.in);
//create a scanner object for input

//get input from the user for rows
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();
System.out.print("\n");

i=1; 
while(i<=rows){  //parent while loop
    j=i; 
  while(j<=rows){
  System.out.print(" ");//print space
  j++;
  }
  j=1;
  while( j<=2*i-1){
  System.out.print(j);//print number
   j++;
  }
  j=2*i; 
   while(j<=2*rows-1){
  System.out.print(" ");//print space
  j++;
   }
   j=1;
  while( j<=2*i-1){
  System.out.print(j);//print number
  j++;
  }
  System.out.print("\n");//move to next line
i++;
}

}


}

Combined Pyramid number pattern 2

Program 2

The Java program allows the user to enter the number of rows then it displays two combined upside-down pyramid number pattern according to the number of rows.

System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();
System.out.print("\n");
i=1;
while( i<=rows){//parent while loop
    j=1; 
  while(j<i){
  System.out.print(" ");//print space
   j++;
  }
  j=1; 
  while(j<2*(rows-i+1)){
