put（int i）
这个 put（int i） 方法 JAVA尼奥。IntBuffer 类用于将给定的int写入当前位置新创建的int缓冲区，然后递增该位置。
null
语法：
public abstract IntBuffer put(int i)
参数： 此方法接受int值 我 作为要写入int缓冲区的参数。
返回值： 这个方法返回这个缓冲区，在其中插入int值。
例外情况： 此方法引发以下异常：
- BufferOverflowException- 如果该缓冲区的当前位置不小于其限制
- ReadOnlyBufferException- 如果这个缓冲区是只读的
以下是说明put（int i）方法的示例：
例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 IntBuffer int capacity = 3 ; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer using put() method ib.put( 8 ); ib.put( 9 ); ib.put( 7 ); ib.rewind(); // print the IntBuffer System.out.println( "Original IntBuffer: " + Arrays.toString(ib.array())); } catch (BufferOverflowException e) { System.out.println( "Exception throws : " + e); } catch (ReadOnlyBufferException e) { System.out.println( "Exception throws : " + e); } } } |
输出：
Original IntBuffer: [8, 9, 7]
例2： 演示BufferOverflowException。
// 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 IntBuffer int capacity = 3 ; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer using put() method ib.put( 8 ); ib.put( 9 ); ib.put( 7 ); System.out.println( "Trying to put the Int at the " + "position more than its limit" ); ib.put( 7 ); // rewind the Intbuffer ib.rewind(); // print the IntBuffer System.out.println( "Original IntBuffer: " + Arrays.toString(ib.array())); } catch (BufferOverflowException e) { System.out.println( "Exception throws : " + e); } catch (ReadOnlyBufferException e) { System.out.println( "Exception throws : " + e); } } } |
输出：
Trying to put the Int at the position more than its limit Exception throws : java.nio.BufferOverflowException
例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 IntBuffer int capacity = 3 ; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity using allocate() method IntBuffer ib = IntBuffer.allocate(capacity); // Creating a read-only copy of IntBuffer // using asReadOnlyBuffer() method IntBuffer ib1 = ib.asReadOnlyBuffer(); System.out.println( "Trying to put the Int value" + " in read only buffer" ); // putting the value in readonly Intbuffer // using put() method ib1.put( 8 ); } catch (BufferOverflowException e) { System.out.println( "Exception throws : " + e); } catch (ReadOnlyBufferException e) { System.out.println( "Exception throws : " + e); } } } |
输出：
Trying to put the Int value in read only buffer Exception throws : java.nio.ReadOnlyBufferException
put（int索引，int i）
java的put（intindex，inti）方法。尼奥。IntBuffer类用于将给定的int写入给定索引处的缓冲区。
语法：
public abstract IntBuffer put(int index, int i)
参数： 此方法将以下参数作为参数：
- 指数 ：将写入int的索引
- 我 ：要写入的int值
返回值： 此方法返回此缓冲区。
例外情况： 此方法引发以下异常：
- IndexOutOfBoundsException- 如果索引为负数或不小于缓冲区的限制
- ReadOnlyBufferException- 如果这个缓冲区是只读的
下面是说明put（int index，int i）方法的示例：
例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 IntBuffer int capacity = 3 ; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer using put() at index 0 ib.put( 0 , 8 ); // putting the value in Intbuffer using put() at index 2 ib.put( 2 , 9 ); // putting the value in Intbuffer using put() at index 1 ib.put( 1 , 7 ); // rewinding the Intbuffer ib.rewind(); // print the IntBuffer System.out.println( "Original IntBuffer: " + Arrays.toString(ib.array())); } catch (IndexOutOfBoundsException e) { System.out.println( "Exception throws : " + e); } catch (ReadOnlyBufferException e) { System.out.println( "Exception throws : " + e); } } } |
输出：
Original IntBuffer: [8, 7, 9]
例2： 展示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 IntBuffer int capacity = 3 ; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer // using put() at index 0 ib.put( 0 , 8 ); // putting the value in Intbuffer // using put() at index 2 ib.put( 2 , 9 ); // putting the value in Intbuffer // using put() at index -1 System.out.println( "Trying to put the value" + " at the negative index" ); ib.put(- 1 , 7 ); } 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
例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 IntBuffer int capacity = 3 ; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity using allocate() method IntBuffer ib = IntBuffer.allocate(capacity); // Creating a read-only copy of IntBuffer // using asReadOnlyBuffer() method IntBuffer ib1 = ib.asReadOnlyBuffer(); System.out.println( "Trying to put the Int value" + " in read only buffer" ); // putting the value in readonly Intbuffer // using put() method ib1.put( 0 , 8 ); } catch (BufferOverflowException e) { System.out.println( "Exception throws : " + e); } catch (ReadOnlyBufferException e) { System.out.println( "Exception throws : " + e); } } } |
输出：
Trying to put the Int value in read only buffer Exception throws : java.nio.ReadOnlyBufferException
