如何将单个数组组合为一个二维数组？

Question

我想分裂显示模式的一维数组到一个2维字符串数组，虽然我遇到了麻烦，我到了分裂显示模式的排序数组点。我的问题：如何将已经排序的单个数组拆分为二维数组？代码（很抱歉的奇怪的变量名）：

public static String[][] OrganizeDisplayModes (DisplayMode[] modes) { 
    int iter = 0; 
    int deltaIter = 0; 
    int rows = 0; 
    int columns = 0; 
    String[][] tobe; 
    //bubble sorting 
    for (int a = 0; a < modes.length - 1; a++) { 
     for(int i = 0; i < modes.length - 1; i++) { 
      if (modes[i].getWidth() < modes[i+1].getWidth()) { 
       DisplayMode change = modes[i]; 
       modes[i] = modes[i+1]; 
       modes[i+1] = change; 
      } 
     } 
    } 
    for(int i = 0; i < modes.length - 1; i++) { 
     if ((modes[i].getWidth() == modes[i+1].getWidth()) && (modes[i].getBitsPerPixel() < modes[i+1].getBitsPerPixel())) { 
      DisplayMode change = modes[i]; 
      modes[i] = modes[i+1]; 
      modes[i+1] = change; 
     } 
    } 
    for(int i = 0; i < modes.length - 1; i++) { 
     if ((modes[i].getWidth() == modes[i+1].getWidth()) && (modes[i].getFrequency() < modes[i+1].getFrequency())) { 
      DisplayMode change = modes[i]; 
      modes[i] = modes[i+1]; 
      modes[i+1] = change; 
     } 
    } 
    for(int i = 0; i < modes.length; i++) { 
     DisplayMode current = modes[i]; 
     System.out.println(i + ". " + current.getWidth() + "x" + current.getHeight() + "x" + 
       current.getBitsPerPixel() + " " + current.getFrequency() + "Hz"); 
    } 

    //fit into string array 
    for (int i = 0; i < modes.length - 1; i++) { 
     if (!(modes[i].getWidth() == modes[i+1].getWidth())) { 
      rows += 1; 
      deltaIter = i - deltaIter; 
      if (deltaIter > columns) 
      columns = deltaIter; 
     } 
    } 
    //split the displaymode array into the two-dimensional string one here 
    tobe = new String[rows][columns]; 
    for (int i = 0; i < rows; i++) { 
     for (int a = 0; a < columns; a++) { 
      if((modes[iter].getWidth() == modes[iter+1].getWidth())) { 
       tobe[i][a] = iter + ". " + modes[iter].toString() + " "; 
      } 
      else 
       break; 
      if (!(iter >= 68)) 
       iter += 1; 
     } 
     if (iter >= 68) 
      break; 
    } 
    tobe[rows-1][columns-1] = (iter + 1) + ". " + modes[iter].toString() + " "; 
    //test to see that it works 
    for (int i = 0; i < rows; i++) { 
     for (int a = 0; a < columns; a++) { 
      if(tobe[i][a] != null) 
       System.out.print(tobe[i][a]); 
      else 
       break; 
     } 
     System.out.println(""); 
    } 
    System.exit(0); 
    return null; 
} 

输出看起来是这样的：

0. 1440x900x32 75Hz 
1. 1440x900x16 75Hz 
2. 1440x900x32 60Hz 
3. 1440x900x16 60Hz 

所有不同的可能的解决方案的。基本上，我想要做的是制作不同分辨率的可读列表，以便用户可以选择所需的分辨率。谢谢。

如何以不同的方式存储信息？当我从C过渡到Java时，我曾经使用过多维数组，但这很痛苦。

public class ScreenType implements Comparable { 
    int width; 
    int height; 
    int color; // not sure what this one was for, assuming 32/16 bit color 
    int hertz; 

    public ScreenType(int w, int h, int c, int h) { 
     width = w; 
     height = h; 
     color = t; 
     hertz = h; 
    } 

    // remember to maintain transitive property, 
    // see JDK documentation for Comparable 
    @Override 
    public int compareTo(Tuple other) { 
    } 

    // getters and setters and whatnot 

    @Override 
    public String toString() { 
     return width + "X" + height + "X" + color+ " " + hertz + "hz"; 
    } 
} 

然后你的屏幕数据存储这样和使用ScreenTypes的ArrayList，如果我没记错的话，将整理根据您的compareTo（）
