Java中的FloatBufferplicate()方法
可以使用类java.nio.FloatBuffer中的plicate()方法创建缓冲区的重复缓冲区。此重复缓冲区与原始缓冲区相同。方法plicate()返回创建的重复缓冲区。
演示此的程序如下所示-
示例
import java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { FloatBuffer buffer1 = FloatBuffer.allocate(n); buffer1.put(4.5F); buffer1.put(1.2F); buffer1.put(3.9F); buffer1.put(7.5F); buffer1.put(5.8F); buffer1.rewind(); System.out.println("The Original FloatBuffer is: " + Arrays.toString(buffer1.array())); FloatBuffer buffer2 = buffer1.duplicate(); System.out.print("The Duplicate FloatBuffer is: " + Arrays.toString(buffer2.array())); } catch (IllegalArgumentException e) { System.out.println("Error!!! IllegalArgumentException"); } catch (ReadOnlyBufferException e){ System.out.println("Error!!! ReadOnlyBufferException"); } } }
上面程序的输出如下-
输出结果
The Original FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8] The Duplicate FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8]
