Start with jigsaw Puzzle (i) _ Simple Java Simulation

       See Android Today, see an open Source Library Android-flipview, and then look at it and go around the jigsaw puzzle, and now I'm going to write a simple jigsaw puzzle game. This will be my second series of articles, today is the first day, the simple Java command line to simulate the realization of the puzzle game. Code:

Package Com.wly.algorithmproblem;

Import Java.util.Scanner;
	/** * Simple Simulation of jigsaw puzzle * @author wly * */public class Picgame {private static int COLUMN = 4;
	
	private static int[][] Elems = new Int[column][column];
		
		public static void Main (string[] args) {int elemsnum = elems.length*elems.length-1; 
			for (int i=0;i<elems.length;i++) {for (int j=0;j<elems[0].length;j++) {Elems[i][j] = i*elems.length + j; //1. Generate random data, random 22 exchange for (int i=0;i<elems.length;i++) {for (int j=0;j<elems[0].length;j++) {int R
				Andom = (int) (Math.random () * elemsnum);
			Exchangeelems (elems,i,j,random/elems.length,random%elems.length);
		
		} printmatrix (Elems);
			while (true) {System.out.print ("Enter X and y:");
			Scanner Scanner = new Scanner (system.in);
			int x = Scanner.nextint ();
			int y = Scanner.nextint ();
			Move (x, y);
		Printmatrix (Elems); The public static void move (int line,int column) {//Check argument legality if (line < 0 | | line > (elems.lengTH-1) | | Column < 0 | |
			Column > (elems.length-1)) {System.out.println ("Incorrect input data, no longer valid range!");
		Return
				} if (line > 0) {//Up if (elems[line-1][column] = = 0) {exchangeelems (Elems, line, column, line-1, column);
			Return } if (line < (elems.length-1)) {//Next if (elems[line+1][column] = = 0) {exchangeelems (Elems, line, column, L
				ine+1, column);
			Return } if (Column > 0) {//left if (elems[line][column-1] = = 0) {exchangeelems (Elems, line, column, line, column-1
				);
			Return  } if (column < (elems.length-1)) {//Right if (elems[line][column+1] = = 0) {exchangeelems (Elems, line, column,
				line, column+1);
			Return
		} System.out.println ("Cannot move current element");
	Return /** * Swap two elements adjacent to a two-dimensional array * @param array * @param x1 * @param y1 * @param x2 * @param y2/private Stati
		c void Exchangeelems (int[][] array,int x1,int y1,int x2,int y2) {int temp = array[x1][y1]; ARRAY[X1][Y1] = Array[x2][y2];
		ARRAY[X2][Y2] = temp; /** * Print two-dimensional matrix * @param matrix/private static void Printmatrix (int[][) matrix {for (int i=0;i<matrix.le
			ngth;i++) {for (int j=0;j<matrix[0].length;j++) {System.out.print (Matrix[i][j] + "");
		} System.out.println (); }
	}
}

Operation Effect:

8 5 6 1 7 0 4 3 9 2 
x and y:2 0 ( 
8 5) 6 1 7 0 (4 3) 9 2 Input x and y:1 0
8 5 0 6 1 7 a 4 3 9 2 
input x and y:0 0
0 8 5 6 1 7 ten 4 3 9 2 
enter x and y:

Things are simple, there is nothing to say, just want to do a simple opening. It is planned to spend 5 days discussing the algorithmic problem of jigsaw puzzle. Then use the Android version of the puzzle for about 5 days. Please look forward to it!

Note: The randomly generated puzzle here is just a simple analog matrix, and in fact the resulting puzzle is about%50, which will be covered in the next blog post.
