Java中的ByteBuffer asIntBuffer()方法
可以使用asIntBuffer()类java.nio.ByteBuffer中的方法将ByteBuffer的视图创建为IntBuffer。此方法不需要任何参数，并且根据需要返回int缓冲区。该缓冲区反映了对原始缓冲区所做的更改，反之亦然。
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 = 50;
try {
ByteBuffer bufferB = ByteBuffer.allocate(n);
IntBuffer bufferI = bufferB.asIntBuffer();
bufferI.put(3);
bufferI.put(9);
bufferI.put(1);
bufferI.put(7);
bufferI.put(4);
bufferI.rewind();
int i;
System.out.print("The IntBuffer is: ");
while ((i = bufferI.get()) != 0) {
System.out.print(i + " ");
}
} catch (IllegalArgumentException e) {
System.out.println("Error!!! IllegalArgumentException");
} catch (ReadOnlyBufferException e) {
System.out.println("Error!!! ReadOnlyBufferException");
}
}
}输出结果
The IntBuffer is: 3 9 1 7 4
