Java中的ShortBufferplicate()方法
可以使用duplicate()类java.nio.ShortBuffer中的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。该方法duplicate()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 {
ShortBuffer buffer1 = ShortBuffer.allocate(5);
buffer1.put((short)12);
buffer1.put((short)91);
buffer1.put((short)25);
buffer1.put((short)18);
buffer1.put((short)30);
buffer1.rewind();
System.out.println("The Original ShortBuffer is: " + Arrays.toString(buffer1.array()));
ShortBuffer buffer2 = buffer1.duplicate();
System.out.print("The Duplicate ShortBuffer 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 ShortBuffer is: [12, 91, 25, 18, 30] The Duplicate ShortBuffer is: [12, 91, 25, 18, 30]
