Getting java.util.InputMismatchException? -

so haven't worked java in while , trying out codingame.com see still remembered. doing tutorial level, has code:

import java.util.*; import java.io.*; import java.math.*;  /** * code below read game information you. * on each game turn, information available on standard input, sent: * -> total number of visible enemies * -> each enemy, name , distance * system wait write enemy name on standard output. * once have designated target: * -> cannon shoot * -> enemies move * -> new info available read on standard input. **/ class player {  public static void main(string args[]) {     scanner in = new scanner(system.in);       // game loop     while (true) {         int count = in.nextint(); // number of current enemy ships within range         string[] enemy = new string[count];         int[] dist = new int[count];         string closeenemy = "";         (int = 0; < count; i++) {             enemy[i] = in.next(); // name of enemy             dist[i] = in.nextint(); // distance cannon of enemy         }         for(int j = 0; j <= count - 1; j++){             if(dist[j] > dist[j+1] ){                 closeenemy = enemy[j];             }             else{                 closeenemy = enemy[j+2];             }         }          // write action using system.out.println()         // debug: system.err.println("debug messages...");          system.out.println(closeenemy); // name of threatening enemy (hotdroid 1 example)     } } } 

and need assuming count 2, need check enemy closer comparing dist variables diferent enemies.

what did this:

import java.util.*; import java.io.*; import java.math.*;  /** * code below read game information you. * on each game turn, information available on standard input, sent: * -> total number of visible enemies * -> each enemy, name , distance * system wait write enemy name on standard output. * once have designated target: * -> cannon shoot * -> enemies move * -> new info available read on standard input. **/ class player {  public static void main(string args[]) {     scanner in = new scanner(system.in);       // game loop     while (true) {         int count = in.nextint(); // number of current enemy ships within range         string[] enemy = new string[count];         int[] dist = new int[count];         string closeenemy = "";         (int = 0; < count; i++) {             enemy[i] = in.next(); // name of enemy             dist[i] = in.nextint(); // distance cannon of enemy         }         for(int j = 0; j <= count - 1; j++){             if(dist[j] > dist[j+1] ){                 closeenemy = enemy[j];             }             else{                 closeenemy = enemy[j+2];             }         }          // write action using system.out.println()         // debug: system.err.println("debug messages...");          system.out.println(closeenemy); // name of threatening enemy (hotdroid 1 example)     } } } 

i tried make work amount of enemies (for count user insert), when test gives me following error:

exception in thread "main" java.util.inputmismatchexception @ player.main on line 24

i have checked , can't find mistake , appreciate on this.

you inputting string or double when program expecting int. following input works without throwing inputmismatchexception:

2 enemy1 1 enemy2 2 

after array out of bounds exceptions can fixed with:

for(int j = 0; j < count - 1; j++){     if(dist[j] > dist[j+1] ){         closeenemy = enemy[j];     } else {         closeenemy = enemy[j+1];     } }
