Read MoreJava Program to mark the current position in this input stream
In this article, we will learn to mark and reset the current position in a file input stream in Java. Marking the current position in an input stream is a crucial functionality provided by Java’s InputStream class. It enables developers to reset the stream to a previously marked position, facilitating efficient data handling, especially in scenarios like re-reading or backtracking within a file. Key Concepts Following are the key concepts we need to know to mark the current position in this input stream − InputStream Class: The InputStream class is an abstract class that represents ...
Read MoreJava Program to convert Java Float to Numeric Primitive Data Types
The Float wrapper class provides methods to convert a Float object into various numeric primitive data types like short, int, float, and double in Java. This is particularly useful when handling float values and representing them in different numeric forms.This article will show two approaches to convert a Float object to numeric primitive types using the Float class methods. Using Float Wrapper Class Methods In this approach, we use predefined methods of the Float class, such as shortValue(), intValue(), floatValue(), and doubleValue(), to convert a Float object into various primitive types. These methods directly perform the required conversions. ...
Read MoreJava Connection getTransactionIsolation() method with example
In this article, we learn the Connection getTransactionIsolation() method in Java, which allows you to determine a database connection's current transaction isolation level. Transaction isolation levels dictate how transactions interact, particularly regarding data locking during reads or writes. What is the getTransactionIsolation() Method? The getTransactionIsolation() method is part of the Connection Interface in Java. It returns an integer constant representing the current isolation level of the database connection. JDBC provides support for 5 transaction isolation levels through the Connection interface − TRANSACTION_NONE: It is represented by an integer value 0 and does not support transactions. ...

Read MoreJava Program to Perform nCr (rcombinations)
In this article, we'll learn to perform nCr (Combinations) in Java. In mathematics, nCr (combinations) is a crucial concept that helps determine how many ways you can choose r items from a set of n items, without considering the selection order. It is widely used in fields like probability, statistics, and combinatorics. What is nCr? The formula for calculating combinations (nCr) is − nCr = n! / (r! × (n - r)!) Where, n! = The factorial of n (product of all integers from 1 to n). r! = The factorial ...
