largest palindrome product in java -


i have written code fourth question of euler project.

the question is: palindromic number reads same both ways. largest palindrome made product of 2 2-digit numbers 9009 = 91 × 99.

find largest palindrome made product of 2 3-digit numbers.

here code:

public class largestpalindromeproduct { private static int product;//integer palindrome number private static string palindrome;//string palindrome  private static int largestpalindrome(){     for(int = 100; i<=999; i++){         for(int k = 100; k<=999; k++){             product = i*k;              palindrome  = integer.tostring(product);              for(int j = 0; j<= palindrome.length()-1; j++){                 if(palindrome.charat(j) == palindrome.length() - 1 - j){                     return product;                 }             }         }     }     return product; } public static void main(string[] args) {     int largestpalindrome = largestpalindrome();     system.out.println(largestpalindrome); } 

}

this code gives 998001 output. can me find problem is?

close, pattern work, must try combinations , return largest one. also, don't short circuit method on mis-match, break out of loop.

try couple changes similar i've added...

public class largestpalindromeproduct {  private static int largestpalindrome() {     int max = 0;     for(int = 100; i<=999; i++) {             for(int k = 100; k<=999; k++) {                 int product = i*k;                 if (product <= max) {                     continue;                 }                 string palindrome  = integer.tostring(product);                 boolean = true;                 for(int j = 0; j<= palindrome.length()-1; j++) {                     if(palindrome.charat(j) != palindrome.charat(palindrome.length() - 1 - j)) {                         = false;                         break;                     }                 }                 if (good)                     max = product;             }         }     }     return max; } public static void main(string[] args) {     int largestpalindrome = largestpalindrome();     system.out.println(largestpalindrome); }
