- Q1. What is difference between == and .equals in java
- Ans.
In Java, == is used for comparing reference equality, while .equals() is used for comparing object equality.
== compares memory addresses of two objects
.equals() compares the actual contents of the objects
For primitive data types, == compares values, while for objects, it compares references
Example: String str1 = new String("hello"); String str2 = new String("hello"); str1 == str2 will be false, but str1.equals(str2) wi
- Q2. What is difference between hash map and hash table
- Ans.
HashMap is non-synchronized and not thread-safe, while HashTable is synchronized and thread-safe.
HashMap allows null values and one null key, while HashTable does not allow null keys or values.
HashMap is faster than HashTable as it is non-synchronized, but HashTable is safer for use in multi-threaded environments.
HashMap is part of the Java Collections Framework, while HashTable is a legacy class.
- Q3. HashMap is not synchronized so its allow the null values and one null key on other hand hash table not null values
- Ans.
HashMap allows null values and one null key, while HashTable does not allow null values.

- Q1. Find rank
You are given a matrix ‘ARR’ having dimensions ‘N*M’. Your task to find the rank of the matrix ‘ARR’.
The rank of a matrix is defined as:
(a) The maximum number of linearly independent column ... - Ans. Row Echelon Form
Approach:
- The idea is based on converting the given input matrix ARR into row echelon form.
- Since we know that the rank of the matrix can not be greater than min(N, M). So we will check if N > M then we will transpose the input matrix ARR since we are using row echelon form so the matrix has to be transformed in such a way that in each row all the elements to the left of the diagonal element must be ze...

For a given two strings, 'str1' and 'str2', check whether they are a permutation of each other or not.
Permutations of each other
Two strings are said to be a permutatio... - Ans. Frequency Array Approach
- The first and the foremost condition for two strings to be the permutations of each other is that the frequency of each element in both of them should be the same.
- It can be proven by a very simple argument that we are only rearranging the letters, and not adding or deleting any character.
- So we allocate an array of size 256 (that is the number of distinct ASCIIacharactersterst to store the freque...

You are given an infinite supply of coins of each of denominations D = {D0, D1, D2, D3, ...... Dn-1}. You need to figure out the total number of ways W, in which you can make a cha...
- Ans. Recursion
- The idea is to use recursion.
- For a particular coin, we have two options either include it or exclude it.
- If we include that coin, then calculate the remaining number that we have to generate so recur for that remaining number.
- If we exclude that coin, then recur for the same amount that we have to make.
- Our final answer would be the total number of ways either by including or excluding.
