FloatBuffer slice() method in Java with Examples
The slice() method of java.nio.FloatBuffer Class is used to creates a new float buffer whose content is a shared subsequence of the given buffer’s content.
The content of the new buffer will start at this buffer’s current position. Changes to this buffer’s content will be visible in the new buffer, and vice versa. The two buffers’ position, limit, and mark values will be independent.
The new buffer’s position will be zero, its capacity and its limit will be the number of floats remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
Syntax :
public abstract FloatBuffer slice()
Return Value: This method returns the new float buffer.
Below are the examples to illustrate the slice() method:
Examples 1:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 10 ;
try {
FloatBuffer fb1 = FloatBuffer.allocate(capacity);
fb1.put( 8 .56F);
fb1.put( 9 .61F);
System.out.println( "Original FloatBuffer: "
+ Arrays.toString(fb1.array()));
System.out.println( "\nposition: " + fb1.position());
System.out.println( "\ncapacity: " + fb1.capacity());
FloatBuffer fb2 = fb1.slice();
System.out.println( "\nshared subsequence FloatBuffer: "
+ Arrays.toString(fb2.array()));
System.out.println( "\nposition: " + fb2.position());
System.out.println( "\ncapacity: " + fb2.capacity());
}
catch (IllegalArgumentException e) {
System.out.println( "IllegalArgumentException catched" );
}
catch (ReadOnlyBufferException e) {
System.out.println( "ReadOnlyBufferException catched" );
}
}
}

Output
Original FloatBuffer: [8.56, 9.61, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
position: 2
capacity: 10
shared subsequence FloatBuffer: [8.56, 9.61, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
position: 0
capacity: 8
Examples 2:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 10 ;
try {
FloatBuffer fb1 = FloatBuffer.allocate(capacity);

fb1.put( 9 .61F);
fb1.put( 0 .56F);
fb1.put( 3 .61F);
System.out.println( "Original FloatBuffer: "
+ Arrays.toString(fb1.array()));
System.out.println( "\nposition: " + fb1.position());
System.out.println( "\ncapacity: " + fb1.capacity());
FloatBuffer fb2 = fb1.slice();
fb2.put( 2 .34F);
fb2.put( 6 .34F);

Output
Original FloatBuffer: [8.56, 9.61, 0.56, 3.61, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
position: 4
capacity: 10
shared subsequence FloatBuffer: [8.56, 9.61, 0.56, 3.61, 2.34, 6.34, 0.0, 0.0, 0.0, 0.0]
position: 2
capacity: 6
