Java program to print the following pattern

Algorithm:

• STEP 1: START
• STEP 2: SET lines=8
• STEP 3: DEFINE i, j
• STEP 4: SET i=1.REPEAT STEP 5 to 14 UNTIL i
• 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
