okay so the last problem was solved. thanks to freakychris for that(although i did manage to figure it out before he replied, but still. so now i got a new problem. and if this one comes through, then finally my game will be complete and you guys can play it if you want. mind u its supposed to work exactly like windows minesweeper. only its not gui.

import java.io.*; class minesweeper { BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); char Mine[][]=new char[20][20]; char Field[][]=new char[20][20]; boolean cond=true; int x,y,r1,r2; char cho; void Miner() { for(int i=0;i<20;i++) { for(int j=0;j<20;j++) { Field[i][j]='#'; double rand=Math.random()*100; if(rand>r1 && rand<r2) Mine[i][j]='@'; else Mine[i][j]='#'; } } } void ValFiller() { for(int i=0;i<20;i++) { for(int j=0;j<20;j++) { if(Mine[i][j]!='@') Mine[i][j]=Char(Seeker(i,j)); } } } char Char(int g) { switch(g) { case 1: return '1'; case 2: return '2'; case 3: return '3'; case 4: return '4'; case 5: return '5'; case 6: return '6'; case 7: return '7'; case 8: return '8'; } return '0'; } int Seeker(int i,int j) { int MineVal=0; for(int k=i-1;k<=i+1;k++) { for(int l=j-1;l<=j+1;l++) { if(k>=0 && l>=0&& k<20 && l<20) { if(Mine[k][l]=='@') MineVal++; } } } return MineVal; } void Exhibit() { System.out.println(); for(int i=0;i<20;i++) { for(int j=0;j<20;j++) { System.out.print(Field[i][j]+" "); } System.out.println(); } } void ExhibitM() { System.out.println(); for(int i=0;i<20;i++) { for(int j=0;j<20;j++) { System.out.print(Mine[i][j]+" "); } System.out.println(); } } void Coords()throws IOException { System.out.println("Enter Co-ordinates:"); System.out.print("X:"); x=Integer.parseInt(br.readLine()); System.out.print("Y:"); y=Integer.parseInt(br.readLine()); } void Choice(char c)throws IOException { System.out.println("What would you like to do?"); System.out.println("R.Reveal the Cell."); System.out.println("F.Flag the Cell as Mine."); System.out.print("Choice:"); cho=(char)br.read(); } void Action() { if(cho=='F') Field[x][y]='F'; else if(cho=='R') { if(Mine[x][y]=='@') { Detonate(); cond=false; } else { Field[x][y]=Mine[x][y]; Reveal(); } } } boolean Adja(int i,int j) { if(i+1>=0 && i+1<20) { if(Field[i+1][j]!='#') return true; } if(i-1>=0 && i-1<20) { if(Field[i-1][j]!='#') return true; } if(j+1>=0 && j+1<20) { if(Field[i][j+1]!='#') return true; } if(j-1>=0 && j-1<20) { if(Field[i][j-1]!='#') return true; } return false; } void Reveal() { for(int i=0;i<20;i++) { for(int j=0;j<20;j++) { if(Mine[i][j]!='@' && Adja(i,j)) Field[i][j]=Mine[i][j]; } } for(int i=19;i>=0;i--) { for(int j=19;j>=0;j--) { if(Mine[i][j]!='@' && Adja(i,j)) Field[i][j]=Mine[i][j]; } } } void DiffLvl()throws IOException { System.out.println("E.Easy"); System.out.println("M.Medium"); System.out.println("H.Hard"); System.out.print("Enter your choice:"); char ch=(char)(br.read()); if(ch=='E') r1=50; r2=60; if(ch=='M') r1=35; r2=70; if(ch=='H') r1=30; r2=70; } void Play()throws IOException { System.out.println("Welcome to ShaunSweeper"); System.out.println("Choose a difficulty level:"); DiffLvl(); Miner(); ValFiller(); while(cond) { Exhibit(); System.out.println(); Coords(); System.out.println(); Choice(); Action(); } } void Activate()throws IOException { Play(); } void Detonate() { for(int i=0;i<20;i++) { for(int j=0;j<20;j++) { if(Mine[i][j]=='@') Field[i][j]='@'; } } Exhibit(); cond=false; } }

theres no use my babbling too much. the program works flawlessly...almost. there seems to be something working with the entry method. try it tout and see the error i get. and please see if u can solve it. i've used blue j for this and hope u can use it too.
