Question

我想知道是否有办法让一个随机生成器使用高度和宽度创建所有不同大小的100000个盒子？我没有任何代码，因为我完全不知道如何做到这一点。

好吧，这是一个应该有效的代码示例。

import java.util.Random;


public final class Test {

  public static final void main(String... aArgs){

      int arrayOfBoxes [][] = new int [10000][3];

      //if you like to use a range
       int START = 1;
       int END = 10000;


      for (int i=0;i<10000;i++)
      {

           Random randomHeight = new Random();
           Random randomWidth = new Random();
           int width = GenerateRandomInteger(START, END, randomHeight);
           int height = GenerateRandomInteger(START, END, randomWidth);


           arrayOfBoxes[i][0] = i ;
           arrayOfBoxes[i][1] = width ;
           arrayOfBoxes[i][2] = height ;

      }
      for (int k=0;k<10000;k++){
          System.out.println("Box #"+ arrayOfBoxes[k][0]);

              System.out.println("Width = " + arrayOfBoxes[k][1]);
              System.out.println("Height = " + arrayOfBoxes[k][2]);

      }

  }  


  private static int GenerateRandomInteger(int aStart, int aEnd, Random aRandom){
    if (aStart > aEnd) {
      throw new IllegalArgumentException("Start cannot exceed End.");
    }
    //get the range, casting to long to avoid overflow problems
    long range = (long)aEnd - (long)aStart + 1;
    // compute a fraction of the range, 0 <= frac < range
    long fraction = (long)(range * aRandom.nextDouble());
    int randomNumber =  (int)(fraction + aStart);    
    return randomNumber;
  }
}
