  1. POUnreachable Code in Tic Tac Toe Program
    text
    copied!<p>I've been researching "dead code" and "unreachable code" for awhile now and I still can't seem to figure out what's going on with this problem in my program. This is a snippet of what I have; the method "gameEnd()" which checks for winners in Tic Tac Toe:</p> <pre><code>private boolean gameEnd() { // Setting local variables int x = xMouseSquare; int y = yMouseSquare; int[][] g = gameBoard; int c = CPU; int h = HUMAN; // Checking for a winner /* Checking columns (xMouseSquare) * Enter the y value, the vertical value, first; then x, the horizontal value, second */ // Set y equal to 0 and then add 1 for (y = 0; y &lt; 3; y++) { // Set CPU c equal to 0 c = 0; // Set x equal to 0 and then add 1 for (x = 0; x &lt; 3; x++) { // Add CPU's value to the game board c += g[x][y]; // If statement returning the absolute value of CPU if (Math.abs(c) == 3) { // If these values are correct, return true; the game ends with CPU win horizontally return true; } } } // If not, return false; game continues until all marks are filled return false; // Set y equal to 0 and then add 1 for (y = 0; y &lt; 3; y++) { // This time, however, set HUMAN h equal to 0 h = 0; // Set x equal to 0 and then add 1 for (x = 0; x &lt; 3; x++) { // Then add HUMAN's value to the game board h += g[x][y]; // If statement returning the absolute value of HUMAN if (Math.abs(h) == -3) { // If these values are correct, return true; the game ends with HUMAN win horizontally return true; } } } // If not, return false; game continues until all marks are filled return false; { /* Checking rows (yMouseSquare) * Enter the x value, the horizontal value, first; then y, the vertical value, second */ // Set x equal to 0 and then add 1 for (x = 0; x &lt; 3; x++) { // Set CPU equal to 0 c = 0; // Set y equal to 0 and then add 1 for (y = 0; y &lt; 3; y++) { // Add CPU's value to the game board, but with y and then x c += g[y][x]; // If statement returning the absolute value of CPU if (Math.abs(c) == 3) { // If these values are correct, return true; the game ends with CPU win vertically return true; } } } // If not, return false; game continues until all marks are filled return false; { // Set x equal to 0 and then add 1 for (x = 0; x &lt; 3; x++) { // This time, however, set HUMAN h equal to 0 h = 0; // Set y equal to 0 and then add 1 for (y = 0; y &lt; 3; y++) { // Then add HUMAN's value to the game board h += g[x][y]; // If statement returning the absolute value of HUMAN if (Math.abs(h) == -3) { // If these values are correct, return true; the game ends with CPU win vertically return true; } } } // If not, return false; game continues until all marks are filled return false; } } } } // error on this bracket; but when I remove it, some of the code above becomes unreachable. Can anyone point to what I'm doing wrong? </code></pre>
