Hi friend,


Code to solve the problem :

import java.io.*;

class Traingle
{
public static void main(String[] args) throws IOException
{
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader bufReader = new BufferedReader(isr);

System.out.println("Enter a integer");
int t = Integer.parseInt(bufReader.readLine());
System.out.println("Integer is " + t);

for(int i=1; i<=t; i++){ //t is the length of the triangle.

for(int space =t-1; space>=0; space--){// for a space between *
System.out.print(" ");
}
for(int j=1; j<=i; j++){
System.out.print("*");
}
System.out.print("\n");
}
}
}
