java - Scanner only accepting input once -

recently, i've been working on noughts , crosses game, i've stumbled upon problem can't seem able fix.

whenever type in first time, works , prints out board, however, point onward, stops checking , printing out board.

        while(inf){         string temp = input.next();         if(playerturn == 1){             if(amountp1 <= 3){                 if(temp.equalsignorecase("00")){                     if(board[0][0] == 0){                         board[0][0] = 1;                         showboard(board);                         playerturn = 2;                         amountp1++;                     }                     else{                         system.out.println("this space occupied!");                     }                 }                 else if(temp.equalsignorecase("01")){                     if(board[0][1] == 0){                         board[0][1] = 1;                         showboard(board);

and method printing out board:

    public static void showboard(int x[][]){     int rownumber = 1;     for(int row = 0 ; row < x.length ; row++){         for(int column = 0 ; column < x[row].length ; column++){             if(x[row][column] == 0){                 if(rownumber <= 2){                 system.out.print(" e");                 rownumber++;                 }                 else if(rownumber == 3){                     system.out.println(" e");                     rownumber = 1;                 }             }             else if(x[row][column] == 1){                 if(rownumber <= 2){                 system.out.print(" x");                 rownumber++;                 }                 else if(rownumber == 3){                     system.out.println(" x");                     rownumber = 1;                 }             }             else if(x[row][column] == 2){                 if(rownumber <= 2){                 system.out.print(" o");                 rownumber++;                 }                 else if(rownumber == 3){                     system.out.println(" o");                     rownumber = 1;                 }             }         }     } } 

also, aware code big mess , there's problably ton of other, more efficient ways this, since new programmer, chose go functionality on efficiency one.

your else if(playerturn == 2) line needs pulled out same level if(playerturn == 1):

if(playerturn == 1){     if(amountp1 <= 3){         //...     }     else if(playerturn == 2){         //...     } } 

should become

if(playerturn == 1){     if(amountp1 <= 3){         //...     } } else if(playerturn == 2) {     //... }
