Java中的IntBufferplicate()方法
可以使用duplicate()java.nio.IntBuffer类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 {
IntBuffer buffer1 = IntBuffer.allocate(n);
buffer1.put(8);
buffer1.put(1);
buffer1.put(3);
buffer1.put(7);
buffer1.put(5);
buffer1.rewind();
System.out.println("The Original IntBuffer is: " + Arrays.toString(buffer1.array()));
IntBuffer buffer2 = buffer1.duplicate();
System.out.print("The Duplicate IntBuffer 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 IntBuffer is: [8, 1, 3, 7, 5] The Duplicate IntBuffer is: [8, 1, 3, 7, 5]
