How to use the ShortBuffer put() method in Java
In Java, the ShortBuffer put() method writes a new value to the buffer at a given index.
The program needs to include the following module to use the ShortBuffer limit() method:
java.nio.ShortBuffer
Syntax
public abstract ShortBuffer put(int index, short s)
Parameters and return value
The FloatBuffer put() method accepts the following parameters:
index: Indicates where to write the new value. It is of typeint.s: The value to be written. It is of type short.
The ShortBuffer put() method throws the following exceptions:
IndexOutOfBoundsException: The function throws this exception if the index is negative or greater than/equal to the buffer’s limit.ReadOnlyBufferException: The function throws this exception if the buffer is read-only.
Examples
The following examples demonstrate how to use the ShortBuffer put() method in Java.
Example 1
Example 1 allocates a capacity of 4 to a buffer and populates it with short values through the ShortBuffer put() method. The program then displays the buffer:
import java.nio.*;
import java.util.*;
public class main {
public static void main(String[] args)
{
try{
System.out.println( "-----Example 1----");
// Example 1
//create a ShortBuffer
ShortBuffer buf = ShortBuffer.allocate(4);
//populate using short values
buf.put(0, (short)50);
buf.put(1, (short)20);
buf.put(2, (short)88);
// print the short buffer
System.out.println( "ShortBuffer "+ Arrays.toString(buf.array()));
System.out.println( "\nPosition: "+ buf.position());
System.out.println( "\nLimit: " + buf.limit());
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception throws: " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws: " + e);
}
}
}Example 2
Example 2 allocates a capacity of 4 to a buffer and populates it with short values through the ShortBuffer put() method. However, a value is put at index 4 that is out of bounds. So, an exception is thrown, as illustrated in the output below:
import java.nio.*;
import java.util.*;
public class main {
public static void main(String[] args)
{
try{
//Example 2
System.out.println( "-----Example 2----");
ShortBuffer buf1 = ShortBuffer.allocate(4);
//populate using short values
buf1.put(0, (short)50);
buf1.put(1, (short)20);
buf1.put(4, (short)88);
// print the short buffer
System.out.println( "ShortBuffer before "+ "setting buffer's limit: "+ Arrays.toString(buf1.array()));
System.out.println( "\nPosition: "+ buf1.position());
System.out.println( "\nLimit: " + buf1.limit());
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception throws: " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws: " + e);
}
}
}Example 3
Example 3 allocates a capacity of 4 to a buffer. The program creates a read-only copy of this buffer through the asReadOnlyBuffer() method and populates it with short values through the ShortBuffer put() method. However, a value cannot be written to the read-only buffer; so an exception is thrown, as illustrated in the output:
import java.nio.*;
import java.util.*;
public class main {
public static void main(String[] args)
{
try{
System.out.println( "-----Example 3----");
ShortBuffer buf2 = ShortBuffer.allocate(4);
//create a readonly buffer
ShortBuffer buf3 = buf2.asReadOnlyBuffer();
//populate using short values
buf3.put(0, (short)50);
buf3.put(1, (short)20);
buf3.put(2, (short)88);
// print the short buffer
System.out.println( "ShortBuffer before "+ "setting buffer's limit: "+ Arrays.toString(buf3.array()));
System.out.println( "\nPosition: "+ buf3.position());
System.out.println( "\nLimit: " + buf3.limit());
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception throws: " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws: " + e);
}
}
