Similarly, you can declare arrays of other types: byte[] anArrayOfBytes; short[] anArrayOfShorts; long[] anArrayOfLongs; float[] anArrayOfFloats; double[] anArrayOfDoubles; boolean[] anArrayOfBooleans; char[] anArrayOfChars; String[] anArrayOfStrings; ...

若要对数字数组进行排序,可以使用Arraysclass中的一种排序方法: int[] a = new int[10000]; . . . Arrays.sort(a); 这种方法使用了快速排序算法的优化版本,这种算法在大多数数据集上都非常有效。 清单3.7中的程序为彩票游戏抽取数字的随机组合。 例如,如果您玩“从49中选择6个数字”彩票,程序可能会打印以...
System.out.println(Arrays.toString(r)); We print the elements of the original and the reversed array. $ java Main.java [3, 4, 5, 6, 7] [7, 6, 5, 4, 3] Multidimensional arrays So far we have been working with one-dimensional arrays. In Java, we can create multidimensional arrays...
Multi-dimensional array type (int[][], String[][], etc.)A new Java array is allocated and each element is converted according to the rules described in this section, including this rule and the base case for one-dimensional arrays. ...
This is exacerbated because Java uses arrays-of-arrays to implement multi-dimensional arrays. A clever copying technique and two new array packages allow for more efficient use of CUDA. 展开 DOI: 10.1145/1808954.1808959 被引量: 53 年份: 2010 ...
