• java - how make jbutton# index take value of int variable? 2 answers

i making game in java. want able check whether level has been visited. came this:

public class leveltracker {    boolean depth1visited = false;   boolean depth2visited = false;   // ..   boolean depth100visited = false;     private boolean leveltracking() {     if (dungeon.depth == 1) {       depth1visited = true;     }     if (dungeon.depth == 2) {       depth2visited = true;     }     // ..     if (dungeon.depth == 100) {       depth100visited = true;     }   } } 

in situation, each depth must checked independently since level might accessed other level. this:

if (depth > deepestdepth) {   deepestdepth = depth; } 

won't work in situation. unless i'm wrong, possible. am, can tell, novice @ this.

what better way this? loop used in situation?

use arrays, can addressed index. can replace ifs , 100 separate variables.

boolean[] depthvisited = new boolean[100];  // default values: false 

then can access array calculating index.

depthvisited[dungeon.depth - 1] = true;  // 0-based index 

no for loop necessary.
