Java program to Integrated triangle pattern using for loop
In this tutorial, we will discuss a concept of Java program to Integrated triangle patterns using for loop in Java language
In Java programming language, we can use for loop ,while loop and do-while loop to display different number (binary, decimal), alphabets or star patterns programs.
In this article, we are going to learn how to Display Integrated triangle star and number patterns using for loop in Java language
Java code to Integrated triangle star patterns
Double Triangle star pattern 1
Program 1
import java.util.Scanner;
class integratedTrianglefor{
public static void main(String args[]){
int i,j,k; //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();
for(i=1; i<=rows; i++){
for(j=1; j<=i; j++){
System.out.print("*"); //print star
}
for(j=i*2; j<rows*2; j++){
System.out.print(" "); //print space
}
for(k=i; k>=1; k--){
System.out.print("*"); //print star
}
System.out.print("\n");
}
}
}
When the above code is executed, it produces the following results
Double Triangle star pattern 2
Program 2
import java.util.Scanner;
class integratedTrianglefor1{
public static void main(String args[]){
int i,j,k; //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();
for(i=rows; i>=1; i--){
for(j=rows; j>=1+rows-i; j--){
System.out.print("*");
}
for(j=i*2; j<rows*2-1; j++){
System.out.print(" ");
}
for(k=1+rows-i; k<=rows; k++){
if(k!=1)
System.out.print("*");
}
System.out.print("\n");
}
}
}
When the above code is executed, it produces the following results

for(j=i*2; j<rows*2-1; j++){
System.out.print(" ");
}
for(k=i; k>=1; k--){
if(k!=rows)
System.out.print(k);
}
System.out.print("\n");
}
}
}
