Java program to print the following pattern

*000*000*
0*00*00*0
00*0*0*00
000***000

Algorithm:

• STEP 1: START
• STEP 2: SET lines=4
• STEP 3: Define i, j
• STEP 4: SET i =1
• STEP 5: REPEAT STEP 6 to 15 UNTIL i <= lines
• STEP 6: SET j=1
• STEP 7: REPET STEP 8 and 9 UNTIL j <= lines
• STEP 8: IF i is equal to j PRINT * ELSE PRINT 0
• STEP 9: SET j = j + 1
• STEP 10: DECREMENT j by 1 and PRINT *
• STEP 11: REPEAT STEP 12 and 13 UNTIL j >=1
• STEP 12: IF i is equals to j PRINT * ELSE PRINT 0
• STEP 13: SET j = j - 1
• STEP 14: PRINT a new line
• STEP 15: SET i = i + 1
• STEP 16: END

Program:

Output:

*000*000*
0*00*00*0
00*0*0*00
000***000
