Here is the source code of the Java program to implement bit array. The Java program is successfully compiled and run on a Linux system. The program output is also shown below. importjava.util.BitSet; publicclassBitArray { privateBitSetbits; publicBitArray(Stringbits) { this.bits=fromString(...
The array() function in PHP is used to create an array. An array is a variable that can store multiple values of the same data type. In this article, we will
Hence, if we return array like this, it will be mandatory to check for nullity in order to avoid NullPointerException in java and this is a recommended coding practice as well. So at the calling end we need to do check like this: 1 2 3 4 5 6 7 8 9 public static void main(Str...
