How do you find the prime numbers from 1 to 100 in Java?

Algorithm

1. STEP 1: START.
2. STEP 2: SET ct =0, n=0, i=1,j=1.
3. STEP 3: REPEAT STEP 4 to STEP 11 until n<25.
4. STEP 4: SET j= 1.
5. STEP 5: SET ct = 0.
6. STEP 6: REPEAT STEP7 to STEP 8 UNTIL j<=i.
7. STEP 7: if i%j = = 0 then ct =ct +1.
8. STEP 8: j = j + 1.

How do you find a list of prime numbers?

As we know, the prime numbers are the numbers that have only two factors which are 1 and the number itself. Thus, there are 25 prime numbers between 1 and 100, i.e. 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
