In Java, to check whether a string is palindrome or not we can create a custom method to do string reversal (As custom method is more efficient and reusable) along with that we can also use two-pointer approach or String reversal approach. A String is known as palindrome String, If the reversed string is equal … Read more
In Java, to check whether a year is a leap year or not we can use conditional statements such as if else or switch statements. For a given input year, we have to print whether the year is leap year or not. In this program we will be using the switch statement to solve this … Read more
In Java, to find a reverse of a string is a common task. We can reverse a string with various methods available, such as using loops like while and for, or using StringBuilder for efficiency. For instance, reversing the String “hi” results in “ih”. In this article we will learn how to find reverse of … Read more
In mathematics, a matrix is a rectangular array of numbers arranged in rows and columns. Matrix multiplication is a vital operation in various applications like graphics transformations, solving systems of linear equations, and in algorithms across scientific computing, engineering, and deep learning. However, multiplying matrices isn’t as straightforward as multiplying individual elements. It involves a … Read more
Matrix addition is a basic arithmetic operation where two matrices of the same dimensions are added together to produce a new matrix. Each element of the resulting matrix is obtained by adding corresponding elements from the two matrices. This operation is vital in data science, physics, engineering, and more, where matrices are used to represent … Read more
In Java, to find percentage and grade of the students based on marks we can use if-else conditional statements or Ternary Operator. For example, if a student’s marks in each subject are 30, 45, 60, 90, and 67, the calculated percentage would be 58.40%, resulting in a grade of E. In this article, we are … Read more
The ternary operator, also known as the conditional operator, is a compact way to express conditional statements in Java. Syntax: Features: Example: Nested Ternary Operators: The ternary operator can also be nested within another ternary operator to express more complex conditional logic. However, nesting ternary operators excessively can reduce code readability and should be used … Read more
In Java, to print maximum among two numbers we can use conditional statements such as if else or switch statements. Here we are using switch statement to print maximum among two. For example, if the input numbers are 4 and 5, then 5 is the maximum number. In this article we will learn how to … Read more
In Java, to print all uppercase alphabets we can use loop concepts such as while loop or for loop. If the input alphabet is A, then the output will be A, B, C…. and Z. If the input alphabet (character) is E, then then output will be E, F, G, ….. till Z. Here, the … Read more
In Java, to print all even numbers in a given range we can use loop concepts such as while loop or for loop. When the user enters any two values, it will print all the even numbers in the range that the user entered. Here inputs are inclusive. For a given input range, suppose 1-10, … Read more
