Answer:

Java constructor is a special method defined in a class whose name s the same as the class name

Explanation:

Java constructor is a special method defined in a class whose name is the same as the class name.

The constructor is called when the object is instantiated to initialize the fields in the object. Constructor can have no arguments or it can carry one or more arguments as per the class design. A default no argument constructor is made available for a class automatically even if one is not explicitly defined.

For example: MyClass c = new MyClass();

This will call the zero argument constructor of MyClass if it is defined or otherwise the default constructor for MyClass.

Ganezh [65]

Answer: 1 time.

Explanation:

A binary function is also known as a half-interval search is a search algorithm to find the position of a given element x within a well-sorted array [].
Binary search compares the target value to the middle element of the array.
It ignores half of the elements just after one comparison.
it compares x with the middle element.

So, the function read an element <u>one time</u> in the array before finding the value.

Suppose you are provided with 2 strings to your program. Your task is to join the strings together so you get a single string wi

Mariulka [41]

Answer:

public class TestImport{

public static void main(String[] args) {

String string1 = args[1];

String string2 = args[2];

System.out.println(string1 +" " +string2);

}

Explanation:

The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);

When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.
