The elements must have a total order and the index of the array can be of any discrete type. For languages where this is not possible, sort an array of integers.
Top 10 Java Programming Coding Interview Questions Answers for programmers Java coding interview questions answers Java coding interview questions are mostly some programming exercises which is asked to be solved in java programming language in limited time during any core Java or J2EE interview.
No matter whether you have 2 years of experience or 4 years of experience, There is always some coding interview question in Java programming job you are applying. Actually questions related to Java Coding are increasingly getting popular on Java interviews for two reasons, first its difficult to crack Java coding interview questions than answering fact based questions like Why String is immutable in Java or Why main is static in Java ; Second reason of popularity of Coding question in Java interviews is read need of good developers who are required to do lot of coding in projects rather than doing some maintenance works.
These Coding interview questions are collected from various Java programming interviews, from friends and colleagues and can be a good starting point to refresh your coding skills before appearing on any Java interviews.
These basics Java Programs and logical questions can also be a good resources for learning programming and to improve your problem solving skills in Java. Any way you may be able to solve and find answers of these Java coding questions by yourself, but if you stuck do a google, and you can get many alternative ways to solve these problem.
Some times knowing more than one way to solve any programming question or coding problem in Java also helps to impress interviewer. This list mainly contains basic programs asked on Interviews.
Write a Java program to replace certain characters from String like public String replace String str, char ch This is a tricky Java coding interview question is asked in one of the written test my friend had appeared recently.
This Java coding question can be solved in multiple way e. They may also ask you to write JUnit test for this function which means handling null, empty string etc. Write a Java program to print Fibonacci series upto ? This is one of the most popular coding interview question asked in Java programming language.
Even though, Writing program for Fibonacci series is one of the basic Java program, not every Java developer get it right in interview.
Again interview can ask to solve this programming interview question, by using recursion or Iteration. This Java programming question also test your problem solving skills and if you come up with an original solution, that may even help.
See here for complete code example of Fibonacci series in Java FizzBuzz problem: Write a Java program that prints the numbers from 1 to But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz" This is also one of the classical programming questions, which is asked on any Java programming or technical interviews.
This questions is very basic but can be very trick for programmers, who can't code, that's why it is used to differentiate programmers who can do coding and who can't. Here is a sample Java program to solve FizzBuzz problem: This is pure Java based Coding exercise. In order to solve this Java coding or programming interview question you need to know What is a Comparator in Java and how to use compare method in Java for sorting Object.
Sorting is one of the most logical and practical question on technical interview and ability to sort Java object is must to code in Java. This article help you to solve this Java coding question by explaining how to sort object in Java using Comparable and Comparator.
Just remember that Comparable has compareTo method and use to sort object based upon there natural order e. A good followup question can also be difference between Comparator and Comparable in Java, so be ready for that.
Design a vending machine in Java which vends Item based upon four denomination of coins and return coin if there is no Item. These kind of problem solving questions in Java are not easy, you need to designdeveloper and write JUnit test within 2 to 3 hours and only good Java developers, with practical coding experience can solve this kind of Java programming question.
What helps you is to keep practicing your coding skill even before interview. See this programming exercise in Java to get yourself going. I personally like to ask programming questions, which test your object oriented design skills e.
Write a Java program to check if a number is Armstrong or not? Another popular logical coding interview questions in Java, which is based on programming logic. In order to answer this programming question, you need to know what is Armstrong number, but that is not a problem because question may specify that and even provide sample input and output.
The key thing to demonstrate is logic to check if a number is Armstrong or not. In most cases, you can not use utility methods defined by logic and you need to produce logic by yourself by using basic operators and methods.
By the way this is also one of the basic programming questions and I have already provided a solution for this. Some of the programming or coding interview question is always based on fundamental feature of Java programming language e. Since writing deadlock proof code is important for a Java developer, programming questions which requires knowledge of concurrency constructs becomes popular coding question asked in Java Interviews.
The deadlock happens if four condition is true e.admin. We are a group of young techies trying to provide the best study material for all Electronic and Computer science students. We are publishing Microcontroller projects, Basic Electronics, Digital electronics, Computer projects and also c/c++, java programs.
This program will read N strings (names) and sort them in Ascending Order. Sorting of N Strings/Names in Ascending Order using Java program //Java program to . Now sort the array in ascending order at the same time swap the positions of the words also.
What is a good and simple Java program for sorting numbers in ascending order? How do I write permutation of a string in Java? Write a java program to convert numbers into words? Can we write C programming in Java? How do I write a program in Java.
