FloatBuffer slice() method in Java
A new FloatBuffer with the content as a shared subsequence of the original FloatBuffer can be created using the method slice() in the class java.nio.FloatBuffer. This method returns the new FloatBuffer that is read-only if the original buffer is read-only and direct if the original buffer is direct.
A program that demonstrates this is given as follows −
Example
import java.nio.*;
import java.util.*;
public class Demo {
public static void main(String[] args) {
int n = 5;
try {
FloatBuffer buffer1 = FloatBuffer.allocate(n);
buffer1.put(4.5F);
buffer1.put(1.2F);
buffer1.put(3.9F);
System.out.println("The Original FloatBuffer is: " + Arrays.toString(buffer1.array()));
System.out.println("The position is: " + buffer1.position());
System.out.println("The capacity is: " + buffer1.capacity());
FloatBuffer buffer2 = buffer1.slice();
System.out.println("
The Subsequence FloatBuffer is: " + Arrays.toString(buffer2.array()));
System.out.println("The position is: " + buffer2.position());
System.out.println("The capacity is: " + buffer2.capacity());
} catch (IllegalArgumentException e) {
System.out.println("Error!!! IllegalArgumentException");
} catch (ReadOnlyBufferException e) {
System.out.println("Error!!! ReadOnlyBufferException");
}
}
}The output of the above program is as follows −
Output
The Original FloatBuffer is: [4.5, 1.2, 3.9, 0.0, 0.0] The position is: 3 The capacity is: 5 The Subsequence FloatBuffer is: [4.5, 1.2, 3.9, 0.0, 0.0] The position is: 0 The capacity is: 2
