java - How to perferm different action depending on user input -

i'm trying make simple game (even without interface). supposed type action attack, heavy , light or block). "enemy" responds "light" action. problem?

 import java.util.scanner;  public class game {     public static void main(string[] args) {         int hp = 10, enemy_hp = 10;         string attack = "attack";         string block = "block";         string heavy = "heavy";         string light = "light";         scanner userinput = new scanner(system.in);         while (enemy_hp > 0 && hp > 0) {             system.out.println("it turn, attack (heavy or light) 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)) { //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 - 3;                     system.out.println("managed hit, hp " + enemy_hp);                 }             } else if (action.equals(light)) { //light attack                 system.out.print("you want light attack");                 if (enemy_block_chance1 == 0) {                     system.out.println(" blocked it");                 } else if (enemy_block_chance1 != 0) {                     enemy_hp = enemy_hp - 1;                     system.out.println(" , managed hit him, hp " + enemy_hp);                 } else if (action.equals(block)) { //block                     system.out.println("you dicided block , rest");                     your_block_chance1 = (int)(math.random() * 1);                     hp++;                 } else if (action.equals(heavy)) { //heavy attack                     system.out.print("you went 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 (enemy_block_chance1 == 0) {                             system.out.println(" blocked it");                         } else if (enemy_block_chance1 != 0) {                             enemy_hp = enemy_hp - 6;                             system.out.println(" , managed hit hard, hp " + enemy_hp);                         }                     }                 }                 system.out.print("it enemy turn, decided "); //enemy turn                  int enemy_action2 = (int)(math.random() * 4);                 if (enemy_action2 == 1) {                     system.out.print("attack you,"); //attack                     if (your_block_chance1 == 0) {                         system.out.println(" blocked it");                     } else if (your_block_chance1 != 0) {                         hp = hp - 3;                         system.out.println(" , didn't block it, hp " + hp);                      }                 } else if (enemy_action2 == 0) { //heavy attack                     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 - 6;                             system.out.println(" , managed hit hard, hp " + hp);                         }                     }                 } else if (enemy_action2 == 3) { //light attack                     system.out.print("do light attack");                     if (your_block_chance1 == 0) {                         system.out.println(" blocked it");                     } else if (your_block_chance1 != 0) {                         hp = hp - 1;                         system.out.println(" , managed hit you, hp " + hp);                     }                 } else if (enemy_action2 == 2) { //block                     system.out.println("block , rest");                     enemy_hp++;                 }             }             if (hp <= 0) {                 system.out.println("you failed");             } else if (enemy_hp <= 0) {                 system.out.println("you won!");             }         }     } } 

misplaced brackets: have removed end bracket } end , added 1 before } else if (action.equals(heavy)) {
