Integer.bitcount() method in Java with example wpaccuracy

In Java, the Integer.bitCount() method is used to count the number of 1-bits in the binary representation of an integer. It returns an integer value representing the number of 1-bits.

Here is an example:

int num = 12345;
int count = Integer.bitCount(num);
System.out.println("Number of 1-bits in " + num + " is " + count);

In this example, we have an integer variable called num with the value of 12345. We call the Integer.bitCount() method with the num variable as an argument, and store the result in the count variable. Finally, we print the result to the console.

The output of this code will be:

Number of 1-bits in 12345 is 6

This means that the binary representation of 12345 has six 1-bits. The Integer.bitCount() method is useful in a variety of applications, such as cryptography and computer graphics.
