Java program to print the following pattern

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81
10 20 30 40 50 60 70 80 90 100

Algorithm:

• STEP 1: START
• STEP 2: SET lines =10
• STEP 3: DEFINE i,j
• STEP 4: SET i=1
• STEP 5: REPEAT STEP 6 to 10 UNTIL i<=lines
• STEP 6: SET j=1
• STEP 7: REPEAT STEP 8 UNTIL j<= i
• STEP 8: PRINT i*j and SET j = j + 1
• STEP 9: PRINT new line
• STEP 10: SET i = i + 1
• STEP 11: END

Program:
