Java program to print the given pattern

Pattern

12344321
123**321
12****21
1******1

In this program, we will try to print the above given pattern on the console in java.

Algorithm:

Step 1: Start.
Step 2: Set lines=4.
Step 3: Define i, j.
Step 4: Set space=0.
Step 5: Set i=0.
Step 6: Repeat step 7 to step 20 until i<lines <li=""></lines<>.
Step 7: Set j=1.
Step 8: Repeat step 9 until j <= space.
Step 9: Print " " and Set J=J+1.
Step 10: Set j=1.
Step 11: Repeat step 12 and step 13 until j<=lines.
Step 12: If j <=(lines-i). Print j Else Print *.
Step 13: Set j=j+1.
Step 14: Decrement j by 1.
Step 15: Repeat step 16 and step 17 until j>0.
Step 16: If j>( lines-i ) then Print * Else Print j.
Step 17: Set j=j-1.
Step 18: If (lines-i) >9 increment space by 1.
Step 19: Print a new line.
Step 20: Set i=i+1.
Step 21: End.

Program:


public class Main
{  
public static void main(String[] args) 
{  
int lines=4;  
int i,j;  
int space=0;  
for(i=0;i<lines;i++)
{
for(j=1;j<=space;j++)
{  
System.out.print(" ");  
}  
for(j=1;j<=lines;j++)
{ 
if(j<=(lines-i))  
System.out.print(j);  
else  
System.out.print("*");  
}  
j--;  
while(j>0)
{  
if(j>lines-i)  
System.out.print("*");  
else  
System.out.print(j);  
j--;  
}  
if((lines-i)>9)  
space=space+1;  
System.out.println("");  
}  
}
}

Output:
12344321
123**321
12****21
1******1
