put(Long i)
java.nio.LongBuffer类的put(Long i)方法用于将给定的Long值写入当前位置的新创建的Long缓冲区中,然后递增该位置。
用法:
public abstract LongBuffer put(Long i)
参数:此方法将Long值i作为要写入Long缓冲区的参数。
返回值:此方法返回此缓冲区,在其中插入Long值。
异常:此方法引发以下异常:
- BufferOverflowException-如果此缓冲区的当前位置不小于其限制
- ReadOnlyBufferException-如果此缓冲区是只读的
下面是说明put(Long i)方法的示例:
范例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 LongBuffer
int capacity = 3;
// Creating the LongBuffer
try {
// creating object of Longbuffer
// and allocating size capacity
LongBuffer ib = LongBuffer.allocate(capacity);
// putting the value in Longbuffer using put() method
ib.put(8);
ib.put(9);
ib.put(7);
ib.rewind();
// prLong the LongBuffer
System.out.println("Original LongBuffer: "
+ 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 LongBuffer: [8, 9, 7]
范例2:演示BufferOverflowException。
// Java program to demonstrate
// put() method
// 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 LongBuffer
int capacity = 3;
// Creating the LongBuffer
try {
// creating object of Longbuffer
// and allocating size capacity
LongBuffer ib = LongBuffer.allocate(capacity);
// putting the value in Longbuffer using put() method
ib.put(8);
ib.put(9);
ib.put(7);
System.out.println("Trying to put the Long at the "
+ "position more than its limit");
ib.put(7);
// rewind the Longbuffer
ib.rewind();
// prLong the LongBuffer
System.out.println("Original LongBuffer: "
+ 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 Long at the position more than its limit Exception throws:java.nio.BufferOverflowException
范例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 LongBuffer
int capacity = 3;
// Creating the LongBuffer
try {
// creating object of Longbuffer
// and allocating size capacity using allocate() method
LongBuffer ib = LongBuffer.allocate(capacity);
// Creating a read-only copy of LongBuffer
// using asReadOnlyBuffer() method
LongBuffer ib1 = ib.asReadOnlyBuffer();
System.out.println("Trying to put the Long value"
+ " in read only buffer");
// putting the value in readonly Longbuffer
// 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 Long value in read only buffer Exception throws:java.nio.ReadOnlyBufferException
put(Long index, Long i)
java.nio.LongBuffer类的put(Long index,Long i)方法用于将给定Long值写入给定索引处的缓冲区。
用法:
public abstract LongBuffer put(Long index, Long i)
参数:此方法将以下参数作为参数:
- index:将要写的Long的索引
- i:要写入的Long值
返回值:此方法返回此缓冲区。
异常:此方法引发以下异常:
- IndexOutOfBoundsException-如果索引为负或不小于缓冲区的限制
- ReadOnlyBufferException-如果此缓冲区是只读的
以下示例说明了put(Long index,Long i)方法:
范例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 LongBuffer
int capacity = 3;
// Creating the LongBuffer
try {
// creating object of Longbuffer
// and allocating size capacity
LongBuffer ib = LongBuffer.allocate(capacity);
// putting the value in Longbuffer using put() at index 0
ib.put(0, 8);
// putting the value in Longbuffer using put() at index 2
ib.put(2, 9);
// putting the value in Longbuffer using put() at index 1
ib.put(1, 7);
// rewinding the Longbuffer
ib.rewind();
// prLong the LongBuffer
System.out.println("Original LongBuffer: "
+ 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 LongBuffer: [8, 7, 9]
范例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 LongBuffer
int capacity = 3;
// Creating the LongBuffer
try {
// creating object of Longbuffer
// and allocating size capacity
LongBuffer ib = LongBuffer.allocate(capacity);
// putting the value in Longbuffer
// using put() at index 0
ib.put(0, 8);
// putting the value in Longbuffer
// using put() at index 2
ib.put(2, 9);
// putting the value in Longbuffer
// 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
范例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 LongBuffer

LongBuffer ib = LongBuffer.allocate(capacity);
// Creating a read-only copy of LongBuffer

LongBuffer ib1 = ib.asReadOnlyBuffer();
System.out.println("Trying to put the Long value"

ib1.put(0, 8);
}
catch (BufferOverflowException e) {
System.out.println("Exception throws:" + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws:" + e);
