Write a Java program to generate random numbers. Write a Java program to detect the deadlocked threads. ģ6) 16 Java LinkedList Programming Examples. These programs are collections related Java coding questions. ģ5) 18 Java ArrayList Programming Examples. Write a Java program to prove strings are immutable in java. You have to find out that missing number. One number will be missing in ‘a’ (2 in this case). Write a Java program to find all pairs of elements in the given array whose sum is equal to a given number. For example, if.

ġ4) How to find all pairs of elements in an array whose sum is equal to given number? This program is one of the logical programs in Java.
For example, If 145 is the given number and 4 is the given digit, then you should find the largest number less than 145 such that it should not contain 4 in it. Write a Java program to find the largest number ‘L’ less than a given number ‘N’ which should not contain a given digit ‘D’. ġ3) How to find largest number less than a given number and without a given digit? For example, If “Java J2EE Java JSP J2EE” is the given string then occurrences of each character in this string is E=4, 2=2, v=2, =4, P=1, S=1, a=4, J=5. Write a Java program to count the number of occurrences of each character in a given string. ġ2) How to count occurrences of each character in a string in Java? This program is one of the matrix related Java programs asked in interview. Write a Java program to perform matrix operations like matrix addition, matrix subtraction, matrix multiplication and transpose of a matrix. ġ1) How to perform matrix operations in Java? Write a Java program to find second largest number in an array of numbers. ġ0) How to find second largest number in an integer array? Write a Java program to find sum of all digits of a given number. ĩ) How to find sum of all digits of a number in Java? In this program, I have discussed five methods to find duplicate elements in the given array. I think array related programs along with string handling programs are the most asked Java programs in interview. Ĩ) How to find duplicate elements in an array? In Java interview coding questions like this, an interviewer mainly check how do you implement logic in you code. For example: 153, 9474, 54748 are some Armstrong numbers. Write a Java program to check whether a given number is Armstrong number or not. A number is called an Armstrong number if it is equal to sum of its digits each raised to the power of number of digits in it. This type of Java programming questions test the coding skills of a candidate. For example, “Mother In Law” and “Hitler Woman” are anagrams. Two strings are said to be anagram if they contain same set of characters but in different order. Write a Java program to check whether two given strings are anagram or not. In this program, you will learn how to check the equality of two arrays using different methods. You will face many Java coding interview questions related to array. One more favorite topic of many interviewers is array. For example, in a string “Better Butter”, duplicate characters and their count is t : 4, e : 3, r : 2 and B : 2. ĥ) How do you check the equality of two arrays in Java? Write a Java program to find duplicate characters and their count in a given string. Ĥ) How to find duplicate characters in a string in Java? You will face many questions on string handling in your interview. The bundle of Java programming interview questions is incomplete without the questions on strings. 3) How do you remove all white spaces from a string in Java?
