Java Programming

hello everyone,
i am having a problem with this program...
can anyone please send me the solution and explain me what the program wants to say ..

here's the program..

Your program is to use the brute-force approach in order to find the Answer to Life, the Universe, and Everything. More precisely... rewrite small numbers from input to output. Stop processing input after reading in the number 42. All numbers at input are integers of one or two digits.
Example


Input:
1
2
88
42
99

Output:
1
2
88
