get()
The get() method of java.nio.FloatBuffer Class is used to reads the float at the given buffer’s current position, and then increments the position.
Syntax :
public abstract float get()
Return Value: This method returns the float value at the buffer’s current position.
Throws: This method throws BufferUnderflowException – If the buffer’s current position is not smaller than its limit, then this exception is thrown.
Below are the examples to illustrate the get() method:
Examples 1:
// Java program to demonstrate// get() method import java.nio.*;import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the FloatBuffer int capacity = 5; // Creating the FloatBuffer try { // creating object of floatbuffer // and allocating size capacity FloatBuffer fb = FloatBuffer.allocate(capacity); // putting the value in floatbuffer fb.put(8.56F); fb.put(9.61F); fb.put(1.24F); fb.rewind(); // print the FloatBuffer System.out.println("Original FloatBuffer: " + Arrays.toString(fb.array())); // Reads the float at this buffer's current position // using get() method float value = fb.get(); // print the Float value System.out.println("\nFloat Value: " + value); // Reads the float at this buffer's next position // using get() method float value1 = fb.get(); // print the Float value System.out.print("\nNext Float Value: " + value1); } catch (IllegalArgumentException e) { System.out.println("\nIllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("\nReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("\nException throws: " + e); } }} |
Output:
Original FloatBuffer: [8.56, 9.61, 1.24, 0.0, 0.0] Float Value: 8.56 Next Float Value: 9.61
Examples 2:
// Java program to demonstrate// get() method import java.nio.*;import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the FloatBuffer int capacity = 3; // Creating the FloatBuffer try { // creating object of floatbuffer // and allocating size capacity FloatBuffer fb = FloatBuffer.allocate(capacity); // putting the value in floatbuffer fb.put(8.56F); fb.put(9.61F); // print the FloatBuffer System.out.println("Original FloatBuffer: " + Arrays.toString(fb.array())); // Reads the float at this buffer's current position // using get() method float value = fb.get(); // print the Float value System.out.println("\nFloat Value: " + value); // Reads the float at this buffer's next position // using get() method System.out.print("\nsince the buffer current position is incremented"); System.out.print(" to greater than its limit "); float value1 = fb.get(); // print the Float value System.out.print("\nNext Float Value: " + value1); } catch (IllegalArgumentException e) { System.out.println("\nIllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("\nReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("\nException throws : " + e); } }} |
Output:
Original FloatBuffer: [8.56, 9.61, 0.0] Float Value: 0.0 since the buffer current position is incremented to greater than its limit Exception throws : java.nio.BufferUnderflowException
get(int index)
The get(int index) method of FloatBuffer is used to read the article at a specified index.
Syntax :
public abstract float get(int index)
Parameters: This method takes index (The index from which the float will be read) as a parameter.
Return Value: This method returns the float value at the given index.
Exception: This method throws IndexOutOfBoundsException. If index is negative or not smaller than the buffer’s limit this exception is thrown.
Below are the examples to illustrate the get(int index) method:
Examples 1:
// Java program to demonstrate// get(int index) method import java.nio.*;import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the FloatBuffer int capacity = 3; // Creating the FloatBuffer try { // creating object of floatbuffer // and allocating size capacity FloatBuffer fb = FloatBuffer.allocate(capacity); // putting the value in floatbuffer fb.put(8.56F); fb.put(9.61F); fb.put(6.61F); // print the FloatBuffer System.out.println("Original FloatBuffer: " + Arrays.toString(fb.array())); // Reads the float at the index 0 of the floatbuffer // using get() method float value0 = fb.get(0); // print the Float value System.out.println("\nFloat Value at index 0: " + value0); // Reads the float at the index 1 of the floatbuffer // using get() method float value1 = fb.get(1); // print the Float value System.out.println("\nFloat Value at index 1: " + value1); // Reads the float at the index 2 of the floatbuffer // using get() method float value2 = fb.get(2); // print the Float value System.out.println("\nFloat Value at index 2: " + value2); } catch (IllegalArgumentException e) { System.out.println("\nIllegalArgumentException catched"); } catch (IndexOutOfBoundsException e) { System.out.println("\nReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("\nException throws : " + e); } }} |
Output:
Original FloatBuffer: [8.56, 9.61, 6.61] Float Value at index 0: 8.56 Float Value at index 1: 9.61 Float Value at index 2: 6.61

Output:
Original FloatBuffer: [8.56, 9.61, 6.61] Float Value at index 0: 8.56 Float Value at index 1: 9.61 Trying to get the float of index greater than its limit Exception thrown: java.lang.IndexOutOfBoundsException
