数组代替问题 真诚请求帮助 已经3天了 都快哭了
import java.util.*;
public class Slide{
private char[][] cells;
public Slide(){
cells= new char[4][4];
}
public Slide(char[][] cells){
for(int row=0; row<cells.length; row++)
for(int column = 0; column<cells[row].length; column++)
this.cells = cells;
}
public void print(){
{
for(char[] a: cells){
for(char c: a){
System.out.print(c+" ");
}
System.out.println();
}
}
}
public void clear(){
for(char[] a : cells) {
Arrays.fill(a, ' ');
}
}
public void project(Slide other){
/*我的问题出在这里 是要合并数值
cells的值比如是
a b c d
e f g h
i j k l
m n o p
other的值比如是
'' '' x ''
'' x '' ''
'' '' x ''
'' x '' ''
合并成为
a b x d
e x g h
i j x l
m x o p
这怎么做啊 请大家帮忙 给点建议都好 谢谢了 */

public void move(int row, int col){
}
}
数组代替，java?
[解决办法]
public class ArrayTest {
/**
* @param args
*/

Slide s2 = new Slide(new char[][]{{' ',' ','x',' '},{' ','x',' ',' '},{' ',' ' ,'x',' '},{' ','x',' ',' '}});
s1.project(s2);
for(char[] cells : s1.getCell()){
System.out.println(Arrays.toString(cells));
}
}
}

}

}
