Java program to print the following pattern

Java Pattern

In this example, we will see a Java program in which we will print the above given pattern.

Algorithm:

Step 1:Start.
Step 2:Set lines=8
Step 3:Define i and j.
Step 4:Set i=1.Repeat Step 5 to 14 Until i<lines< li=""></lines<>
Step 5:Set j=1.
Step 6:Repeat Step 7 and 8 Until j <=(lines/2).
Step 7:IF j is equals to i Print j
else if i is greater than 4 and j equals (lines-i) Print j
else Print " ".
Step 8:j = j + 1.
Step 9:j = j – 2.
Step 10:Repeat Step 11 and 12 Until j > 0.
Step 11:: if j is equals to i Print j
else if i is greater than 4 and j equals (lines-i) then Print j
else Print " ".
Step 12:j = j – 1.
Step 13:Print a new line.
Step 14:i = i + 1.
Step 15:End.

Program:


public class Main
{  
public static void main(String []args)
{  
int lines=8;  
int i,j;  
for(i=1;i<lines;i++){// this loop is used to print the lines  
for(j=1;j<=lines/2;j++){// this loop is used to print numbers  
if(i==j)
{  
System.out.print(j);  
}  
else if(i>4 && j==lines-i)
{  
System.out.print(j);  
}  
else
{  
System.out.print(" ");  
}  
}  
j=j-2;  
while(j>0)
{ 
//this loop is used to print numbers  
if(i==j)
{  
System.out.print(j);  
}  
else if(i>4 && j==lines-i)
{  
System.out.print(j);  
}  
else
{  
System.out.print(" ");  
}  
j--;  
}  
System.out.println("");  
}  
}  
}

Output:
