Read MoreGet the Triplets in an Array Whose Sum is Equal to a Specific Number in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to get all the triplets in the array whose sum is equal to a specific number. Here triplets refer to any three elements of the array which meet a specific condition. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {3, 4, 25, 6, 13, 9}. ...
Read MoreHow to find all leaders in an array in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find leaders in an array. An element is a leader if it is greater than all the elements to its right side. Let’s start! To Show You Some Instances Instance-1 Suppose the original array is {16, 17, 4, 3, 11, 14, 23, 2, 6, 10}. After finding leaders in an array the result will be − 23 10 Instance-2 Suppose the original array is {16, 17, 4, 3, 5, 6, 9, 1, ...
Read MoreCompare Two Different Files Line by Line in Java
In this article, we will compare two different text files which are saved in our system. We will check line by line of each text file, by comparing those we can identify the similarities and differences. Let’s see how we can do it by using the Java programming language. To Show You Some Instances Instance-1 Below figure depict two different text files with same content and hence output will be two files with same content. Instance-2 Below represents two files, say file1.txt and file2.txt with their content. file1.txt This is amazing. Java Language. file2.txt This is amazing. Python ...
Read MoreFind First and Last Word of a File Containing String in Java
As per the problem statement, we need to find the first and last word of the given String. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose there is String “Java is a well-known high-level, class-based object-oriented programming language that Sun Microsystems created and first distributed in 1995. Over 3 billion devices run Java, which is currently owned by Oracle” After printing the first and last word of this String i.e “Java” and “Oracle”. Instance-2 Suppose there is String “For the creation of their desktop, web, ...
Read MoreSeparate Odd and Even Elements into Two Separate Arrays in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to separate odd and even elements into two separate arrays and print the result. A number is said to be an even number if it is divisible by 2, else the number is an odd number. Note − The array must be an integer array. In this article, you will see how to separate even and odd numbers of an array into two different arrays by using Java programming language. Let’s start. To Show ...
