Java 中的 ByteBuffer asShortBuffer() 方法
java 8object oriented programmingprogramming
可以使用 java.nio.ByteBuffer 类中的 asShortBuffer() 方法将 ByteBuffer 视图创建为 ShortBuffer。此方法不需要参数，并根据需要返回一个短缓冲区。此缓冲区反映了对原始缓冲区所做的更改，反之亦然。
下面给出了一个演示此操作的程序 −
示例
import java.nio.*;
import java.util.*;
public class Demo {
public static void main(String[] args) {
int n = 50;
try {
ByteBuffer bufferB = ByteBuffer.allocate(n);
ShortBuffer bufferS = bufferB.asShortBuffer();
bufferS.put((short)5);
bufferS.put((short)9);
bufferS.put((short)2);
bufferS.put((short)8);
bufferS.put((short)3);
bufferS.rewind();
short s;
System.out.print("The ShortBuffer is: ");
while ((s = bufferS.get()) != 0) {
System.out.print(s + " ");
}
} catch (IllegalArgumentException e) {
System.out.println("Error!!! IllegalArgumentException");
} catch (ReadOnlyBufferException e){
System.out.println("Error!!! ReadOnlyBufferException");
}
}
}
输出
The ShortBuffer is: 5 9 2 8 3
