The isDirect() method of java.nio.ShortBuffer is used to check whether or not this short buffer is direct.
Syntax:
public abstract boolean isDirect()
Return Value: The method returns true if and only if, this buffer is direct
Below programs illustrate the use of isDirect() method:
Program 1:
// Java program to demonstrate // isDirect() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { short [] array = { 10000 , 10640 , 10189 , - 2000 , - 16780 }; // creating short array ShortBuffer shortBuf1 = ShortBuffer.wrap(array); // checking if the array is Direct or not if (shortBuf1.isDirect()) { System.out.println( "Short buffer is direct." ); } else { System.out.println( "Short buffer is not direct." ); } } } |
Short buffer is not direct.
Program 2:
// Java program to demonstrate // isDirect() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { ByteBuffer b = ByteBuffer.allocateDirect( 512 ); ShortBuffer shortBuf = b.asShortBuffer(); // checking if the array is Direct or not if (shortBuf.isDirect()) { System.out.println( "Short buffer is direct." ); } else { System.out.println( "Short buffer is not direct." ); } } } |
Short buffer is direct.
