java - Can't understand why my || is not working -


i'm trying make simple game (even without interface). supposed type action (attack or block). why (enemy_hp > 0 || hp > 0) statement doesn't work? loop goes forever.

public class game {     public static void main(string[] args){          int hp = 10, enemy_hp = 10;         string attack = "attack";         string block = "block";         scanner userinput = new scanner (system.in);         while (enemy_hp > 0 || hp > 0) {              system.out.println("it turn, attack or try block");             int your_block_chance1 = (int) (math.random() * 4); //chance block attack             int enemy_block_chance1 = (int) (math.random() * 4);             string action = userinput.next();              if (action.equals(attack)){                 system.out.print("you attacked enemy , ");                 if (enemy_block_chance1 == 0) {                     system.out.println("he blocked it");                 }                 else if (enemy_block_chance1 != 0){                     enemy_hp = enemy_hp - 2;                     system.out.println("managed hit, hp " +enemy_hp);                 }             }                    else if (action.equals(block)){                 system.out.println("you dicided block");                 your_block_chance1 = 0;              }             system.out.print("it enemy turn, decided ");             int enemy_action = (int) (math.random() * 2);             if (enemy_action == 1){                 system.out.print("attack you,");                 if (your_block_chance1 == 0){                     system.out.println(" blocked it");                 }                 else if (your_block_chance1 != 0){                     hp = hp - 2;                     system.out.println(" , didn't block it, hp " +hp);                  }             }             else if (enemy_action != 1){                 system.out.print("do heavy attack");                 int heavy_attack_chance = (int) (math.random() * 2);                 if (heavy_attack_chance == 1){                     system.out.println(" failed");                 }                 else if (heavy_attack_chance != 1){                     if (your_block_chance1 == 0){                         system.out.println(" blocked it");                     }                     else if (your_block_chance1 != 0){                         hp = hp - 4;                         system.out.println(" , managed hit hard, hp " +hp);                      }                 }             }         }         if (hp <= 0){             system.out.println("you failed");         }         else if (enemy_hp <= 0){             system.out.println("you won!");         }     } }

you want while stop when 1 of player die? should rather put &&. because || never false except if 2 players hp below 0.
