DoubleBuffer equals() method in Java with Examples

There is equality between two double buffers if, and only if the elements are of the same type, there are an equal number of remaining elements, and the two sequences of elements are point-by-point equivalent when taken to be considered irrespective of where they started. The java.nio.DoubleBuffer class has an equals() function. To determine if a buffer is equal to another object, utilize the DoubleBuffer Class.

If (a == b) || (Double.isNaN(a) && Double.isNaN(b)), then two double elements, a and b, are considered equivalent by this function. In contrast to Double.equals(Object), the values -0.0 and +0.0 are regarded as equal. There is no other type of object that is equivalent to a double buffer.

Syntax:

Parameters: The object to which this buffer is to be compared is called obj, and it is passed as an argument to this method.

Return Value: If and only if the given object is equal to this buffer, the method returns true.

Example 1:

The code illustrates how two DoubleBuffer instances are compared to see if they are equal. The same capacity is used to construct doublebuff1 and doublebuff2, two DoubleBuffer objects. The identical values are entered into both buffers, and they are subsequently rewound to return to zero positions. They are compared using the equals() method after their contents have been shown. The equals() function determines whether the content, position, limit, and mark of the buffers are equal.

Implementation:

FileName: BufferEqualExample1.java

Output:

 The DoubleBuffer 1 is given by : [9.52, 0.0, 0.0, 0.0, 8.210000038146973, 0.0, 0.0, 0.0, 0.0, 0.0] The DoubleBuffer 2 is given by: [9.52, 0.0, 0.0, 0.0, 8.210000038146973, 0.0, 0.0, 0.0, 0.0, 0.0] Both Doublebuffers are equal 

Example 2:

Two DoubleBuffer objects are generated in this code, doublebuff1 with a capacity of 10 and doublebuff2 with a capacity of 5. The identical values are entered into each buffer, and they are then reconnected. Though doublebuff1 and doublebuff2 have the same information up to their respective limitations, doublebuff1's capacity is more than doublebuff2's. Therefore, their internal states are different. These buffers are compared using the equals() method, which looks for equivalence in the following areas: content, position, limit, and mark. The buffers are not regarded as equal because of their varying capacities, and the output shows this difference.

Implementation:

FileName: BufferEqualExample2.java

Output:

 The DoubleBuffer 1 is given by : [9.52, 0.0, 0.0, 0.0, 8.210000038146973, 0.0, 0.0, 0.0, 0.0, 0.0] The DoubleBuffer 2 is given by: [9.52, 0.0, 0.0, 0.0, 8.210000038146973] Both Doublebuffers are not equal
