Java ShortBuffer put(int, short)用法及代码示例

java.nio.ShortBuffer类的put()方法用于将给定的short写入给定索引处的该缓冲区。

用法：

public abstract ShortBuffer put(int index, short s)

参数：

index：此参数指定写入短路的索引。它是可选的。
s：此参数指定要写入的短值

返回值：此方法返回此缓冲区。

异常：

IndexOutOfBoundsException-如果index为负或不小于缓冲区的限制。
ReadOnlyBufferException-如果此缓冲区是只读的

以下示例程序旨在说明put()方法：

程序1:：

// Java program to demonstrate put() method 
  
import java.nio.*; 
import java.util.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Declaring the capacity of the ShortBuffer 
        int capacity = 3; 
  
        // Creating the ShortBuffer 
        try { 
  
            // creating object of shortbuffer 
            // and allocating size capacity 
            ShortBuffer sb 
                = ShortBuffer.allocate(capacity); 
  
            // putting the value in shortbuffer 
            // using put() at index 0 
            sb.put(0, (short)400); 
  
            // putting the value in shortbuffer 
            // using put() at index 2 
            sb.put(2, (short)1000); 
  
            // putting the value in shortbuffer 
            // using put() at index 1 
            sb.put(1, (short)30); 
  
            // rewinding the shortbuffer 
            sb.rewind(); 
  
            // print the ShortBuffer 
            System.out.println("Original ShortBuffer:"
                               + Arrays.toString(sb.array())); 
        } 
  
        catch (IndexOutOfBoundsException e) { 
  
            System.out.println("Exception throws:" + e); 
        } 
  
        catch (ReadOnlyBufferException e) { 
  
            System.out.println("Exception throws:" + e); 
        } 
    } 
}

输出：

Original ShortBuffer:[400, 30, 1000]

程序2:：
演示IndexOutOfBoundsException。

// Java program to demonstrate put() method 
  
import java.nio.*; 
import java.util.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Declaring the capacity of the ShortBuffer 
        int capacity = 3; 
  
        // Creating the ShortBuffer 
        try { 
  
            // creating object of shortbuffer 
            // and allocating size capacity 
            ShortBuffer sb 
                = ShortBuffer.allocate(capacity); 
  
            // putting the value in shortbuffer 
            // using put() at index 0 
            sb.put(0, (short)31); 
  
            // putting the value in shortbuffer 
            // using put() at index 2 
            sb.put(2, (short)49); 
  
            // putting the value in shortbuffer 
            // using put() at index -1 
            System.out.println("Trying to put the value"
                               + " at the negative index"); 
            sb.put(-1, (short)27); 
        } 
  
        catch (IndexOutOfBoundsException e) { 
  
            System.out.println("Exception throws:" + e); 
        } 
  
        catch (ReadOnlyBufferException e) { 
  
            System.out.println("Exception throws:" + e); 
        } 
    } 
}

输出：

Trying to put the value at the negative index
Exception throws:java.lang.IndexOutOfBoundsException

程序3:：演示ReadOnlyBufferException。

// Java program to demonstrate put() method 
  
import java.nio.*; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Declaring the capacity of the ShortBuffer 
        int capacity = 3; 
  
        // Creating the ShortBuffer 
        try { 
  
            // creating object of shortbuffer 
            // and allocating size capacity 
            // using allocate() method 
            ShortBuffer sb 
                = ShortBuffer.allocate(capacity); 
  
            // Creating a read-only copy of ShortBuffer 
            // using asReadOnlyBuffer() method 
            ShortBuffer sb1 = sb.asReadOnlyBuffer(); 
  
            System.out.println("Trying to put the float value"
                               + " in read only buffer"); 
  
            // putting the value in readonly shortbuffer 
            // using put() method 
            sb1.put(0, (short)13); 
        } 
  
        catch (BufferOverflowException e) { 
  
            System.out.println("Exception throws:" + e); 
        } 
  
        catch (ReadOnlyBufferException e) { 
  
            System.out.println("Exception throws:" + e); 
        } 
    } 
}

输出：

Trying to put the float value in read only buffer
Exception throws:java.nio.ReadOnlyBufferException
