FloatBuffer equals() method in Java
The equality of two buffers can be checked using the method equals() in the class java.nio.FloatBuffer. Two buffers are equal if they have the same type of elements, the same number of elements and same sequence of elements. The method equals() returns true if the buffers are equal and false otherwise.
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);
buffer1.put(7.5F);
buffer1.put(5.8F);
buffer1.rewind();
System.out.println("The first FloatBuffer is: " + Arrays.toString(buffer1.array()));
FloatBuffer buffer2 = FloatBuffer.allocate(n);
buffer2.put(4.5F);
buffer2.put(1.2F);
buffer2.put(3.9F);
buffer2.put(7.5F);
buffer2.put(5.8F);
buffer2.rewind();
System.out.println("The second FloatBuffer is: " + Arrays.toString(buffer2.array()));
boolean flag = buffer1.equals(buffer2);
if (flag)
System.out.println("
Both the buffers are equal");
else
System.out.println("
Both the buffers are not equal");
} 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 first FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8] The second FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8] Both the buffers are equal
