ByteBuffer toString() method in Java with Examples
Last Updated :

The toString() method of ByteBuffer class is the inbuilt method used to returns a string representing the data contained by ByteBuffer Object. A new String object is created and initialized to get the character sequence from this ByteBuffer object and then String is returned by toString(). Subsequent changes to this sequence contained by Object do not affect the contents of the String.
Syntax:
public abstract String toString()
Return Value: This method returns the String representing the data contained by ByteBuffer Object.
Below programs illustrate the ByteBuffer.toString() method:
Example 1:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 5 ;
ByteBuffer bb1 = ByteBuffer.allocate(capacity);
bb1.put(( byte ) 10 );
bb1.put(( byte ) 20 );
System.out.println( "Original ByteBuffer: "
+ Arrays.toString(bb1.array()));
String value = bb1.toString();
System.out.println( "\nstring representation of ByteBuffer: "
+ value);
}
}
|
Output:
Original ByteBuffer: [10, 20, 0, 0, 0]
string representation of ByteBuffer: java.nio.HeapByteBuffer[pos=2 lim=5 cap=5]
Example 2:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 4 ;
ByteBuffer bb1 = ByteBuffer.allocate(capacity);
bb1.put(( byte ) 10 )
.put(( byte ) 20 )
.put(( byte ) 30 )
.put(( byte ) 40 );
System.out.println( "Original ByteBuffer: "
+ Arrays.toString(bb1.array()));
String value = bb1.toString();
System.out.println( "\nstring representation of ByteBuffer: "
+ value);
}
}
|
Output:
Original ByteBuffer: [10, 20, 30, 40]
string representation of ByteBuffer: java.nio.HeapByteBuffer[pos=4 lim=4 cap=4]
