get()
The get() method of java.nio.IntBuffer Class is used to reads the int at the given buffer’s current position, and then increments the position.
Syntax :
public abstract int get()
Return Value: This method returns the int 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 IntBuffer int capacity = 5; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(8); ib.put(9); ib.put(1); ib.rewind(); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at this buffer's current position // using get() method int value = ib.get(); // print the Int value System.out.println("Int Value: " + value); // Reads the Int at this buffer's next position // using get() method int value1 = ib.get(); // print the Int value System.out.print("Next Int Value: " + value1); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("ReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("Exception throws: " + e); } }} |
Output:
Original IntBuffer: [8, 9, 1, 0, 0] Int Value: 8 Next Int Value: 9
Examples 2: To demonstrate java.nio.BufferUnderflowException
// 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 IntBuffer int capacity = 3; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(8); ib.put(9); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at this buffer's current position // using get() method int value = ib.get(); // print the Int value System.out.println("Int Value: " + value); // Reads the Int at this buffer's next position // using get() method System.out.print("Since the buffer current position is incremented"); System.out.print(" to greater than its limit "); int value1 = ib.get(); // print the Int value System.out.print("Next Int Value: " + value1); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("ReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("Exception throws : " + e); } }} |
Output:
Original IntBuffer: [8, 9, 0] Int Value: 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 IntBuffer is used to read the article at a specified index.
Syntax :
public abstract int get(int index)
Parameters: This method takes index (The index from which the int will be read) as a parameter.
Return Value: This method returns the int 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 IntBuffer int capacity = 3; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(8); ib.put(9); ib.put(6); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at the index 0 of the Intbuffer // using get() method int value0 = ib.get(0); // print the Int value System.out.println("Int Value at index 0: " + value0); // Reads the Int at the index 1 of the Intbuffer // using get() method int value1 = ib.get(1); // print the Int value System.out.println("Int Value at index 1: " + value1); // Reads the Int at the index 2 of the Intbuffer // using get() method int value2 = ib.get(2); // print the Int value System.out.println("Int Value at index 2: " + value2); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (IndexOutOfBoundsException e) { System.out.println("ReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("Exception throws : " + e); } }} |
Output:
Original IntBuffer: [8, 9, 6] Int Value at index 0: 8 Int Value at index 1: 9 Int Value at index 2: 6
Examples 2: To demonstrate IndexOutOfBoundsException
// 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 IntBuffer int capacity = 3; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(6); ib.put(8); ib.put(12); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at the index 0 of the Intbuffer // using get() method int value0 = ib.get(0); // print the Int value System.out.println("Int Value at index 0: " + value0); // Reads the Int at the index 1 of the Intbuffer // using get() method int value1 = ib.get(1); // print the Int value System.out.println("Int Value at index 1: " + value1); // Reads the Int at the index 2 of the Intbuffer // using get() method System.out.println("Trying to get the Int" + " of index greater than its limit "); int value2 = ib.get(4); // print the Int value System.out.println("Int Value at index 2: " + value2); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (IndexOutOfBoundsException e) { System.out.println("Exception thrown: " + e); } catch (BufferUnderflowException e) { System.out.println("Exception throws : " + e); } }} |
Output:
Original IntBuffer: [6, 8, 12] Int Value at index 0: 6 Int Value at index 1: 8 Trying to get the Int of index greater than its limit Exception thrown: java.lang.IndexOutOfBoundsException
