Answer:
It can be 100001, 100000,000001,000000
Hence, answer is 4.
its also can be found through 2C2 *2 = 2!/0! *2 =2*2 =4
Explanation:
The answer is straight forward, we have 2 empty places and we can select from 2 items, and hence its 2C2, and now we can arrange them as well, and since we can arrange in 2 ways, hence a total number of possibility = 2 * 2C2 = 4, which is the required answer.
Answer:
isSelected()
Explanation:
The isSelected() method of a radio button returns true if that button is on and false otherwise. This method is defined in the class javax.swing.AbstractButton.

Answer:
The answer is "option iii" .
Explanation:
In the given question it is defined that a class "Rectangle" is defined in the class a parameter constructor is created that accepts two parameters. In this question, we create an instance of the class. In object creation first, we define class name then object name and use new keyword in the Instance of class and pass parameters.
- In option i), An object name is used first and then class name. It is not correct.
- In option ii), In instance creation of the class, we do not use class keyword that's why it is wrong.
Both numeric and non-numeric data have different ASCII codes, that will be the first difference. Second, numeric data are stored in float, double, and int variables while non-numeric data are stored in char. However, both can be stored in a String variable if and only if the desired data to be stored will not be used for computuation using mathematical operations such as addition.
To store a non-numeric data in an array, the array must first be declared as a String variable array while a numeric data can be stored in an array once the array which will store the numeric data is declared as an integer, double, or float variable.
