100

this operator, often used in boolean expressions, has a lower precedence than logical AND (&&) but higher precedence than logical OR (||) in Java, and can lead to some confusing behavior when combined with if-else statements

XOR

200

Simplify (A || B || C) && (!A || !B) && (C || !B);

C || (!A && !B);

300

Simplify 

!(A && (B || C)) || (A && (B || C));

B || C;

400

Simplify 

(A && B) || (!A && !B) || (A && !B);

100

This keyword is used to create a while loop with the loop code coming before the while expression

do while

200

local

300

In a for loop, if the loop is performed n times, the check is performed this many times.

n+1

400

This technique is used to improve program performance when performing recursion where recursive values are repeated and iteration where values are repeated.

Memoization

500

for (int i = -1; i <k-2; i++)

{

     if ((i+2)*(i-2) < x)

          System.out.print("Hello");

}

This is the maximum number of times "Hello" print if x is some integer.

 k-1

Classes

100

In Java, this class contains the main method and is in charge of running other classes.

Driver class

200

In java, this concept is when you protect sensitive fields from being modified by outside classes. They can only be modified through public setter and getter methods from within the class.
