下面是一个简单的示例,演示如何输出一个包含整数的二维数组: publicclassPrint2DArray{publicstaticvoidmain(String[]args){int[][]array={{1,2,3},{4,5,6},{7,8,9}};for(inti=0;i<array.length;i++){for(intj=0;j<array[i].length;j++){System.out.print(array[i][j]+" ");}System.out....
int[][] src=new int[][]{ //假定原数组是这样的 {1,2,3},{4,5,6},{7,8,9},{10,11,12},{13,14,15} };//以原数组的情况生成新数组的大小 int[][] target=new int[src[0].length][src.length];for(int i=0;i<src.length;i++){ for(int j=0;j<src[i].length;j...

Re: [JAVA2D] How to get a 2D array of pixel values (0-255?)of a 8-bit BMP file? It might be too late to help your project since you sounded in a hurry, but here's a reply to the question anyway: As of Java 1.5, I think ImageIO can read BMP's fine....
public class Main { public static void main(String[] args) { int[][] twoDArray = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}; int[] oneDArray = convertTo1DArray(twoDArray); // 打印转换后的一维数组 for (int num : oneDArray) { System.out.print(num + " "); } } public ...

1、当我们在Array中放置不同类型的数据时，我们无法再对每个数据的type做定义。 ["小明",[90,87,88...
fastutil - fastutil extends the Java™ Collections Framework by providing type-specific maps, sets, lists and queues with a small memory footprint and fast access and insertion; provides also big (64-bit) arrays, sets and lists, and fast, practical I/O classes for binary and text files. ...
(Note that as mentioned "crop" and integral translation merely forward the tile requests to the source so you can't expand the data via those operations.) Obviously expanding the palette-color data to RGB will increase the memory footprint but this way you are assured of obtaining a valid ...
