Answer:

The correct answer for the given question is option(c) i.e new

The new keyword allocates a memory for the object .

To create instance we follow following syntax

classname objectname =new classname();

create, =,object ,is are not any keyword to instantiating an object.

What is printed by the following program? var isRaining = false; var isCloudy = false; var isSunny = !isRaining && !isCl

hram777 [196]

Answer:

The output to this given question is "Is it warm: true".

Explanation:

In this question firstly two-variable defines that are isRaining and isCloudy. In those variables assign false value. Then we define another variable that is isSunny. In isSunny variable, we check condition that is if variable isRaining not AND (logical gate) variable isCloudy not equal to isSunny. The AND logical gate is used to check that both condition is true or not. Then we define another variable that is isWarm. In this variable, we check condition if isSunny OR (logical operator) isSummer is true. The OR operator is used to check in both value if one condition will true it will print true. At the last will print the value.
