eclipse - Determining whether a number is prime or not in Java using for loops -

i'm new java , i've acquired programming experience on past year python , c++; however, find java lot more confusing. trying here determine whether or not number (user input) prime or not through use of loops. here code have far:

public static boolean isprime(int x) {     boolean prime = true;     if (x % 2 == 0)         prime = false;     if (x % 2 != 0)     {         (int = 3; i*i <= x; i+=2)         {             if (x % == 0)                 prime = false;         }     }     return prime; } 

i've been stuck on quite time , if me figure out, that'd great.

your solution returns true 1 , false 2

public static boolean isprime(int x) {     if(x<2)     return false;      if(x==2)     return true;     // boolean prime = true; dont need variavle     if (x % 2 == 0)         return false; // using return faster dont need more conditions // also, dont need if. use else, if dont want return //            (int = 3; i*i <= x; i+=2)         {             if (x % == 0)                 return false;         }      return true; }
