We use cookies to ensure you have the best browsing experience on our website. Java Method Overloading In this article, you’ll learn about method overloading and how you can achieve it in Java with the help of examples. This method returns the value obtained by reversing the order of the bits in the two's complement binary representation of the specified long value. Java Long valueOf(String s) Method. How do I get a method's execution time? Yes, we can overload the main method in java. Java String To Long Examples. We have to pass the long value as argument to toString () method. Java Long compareTo () Method The compareTo () method of Java Long class is used to compare two long objects numerically. We will specify the sleep time as an argument of the sleep method. In the following example we shall convert a number of long datatype to string by using Long.toString () function. One of the commonly used method is the Join Method in Java. Parameters: This method do not take any parameters. public long longValue() Parameters. getLong() method is available in java.time package. Program 2: For a very large no. Java printf() printf() method is not only there in C, but also in Java. edit Applications of Java long to String by overriding toString() In java, the toString() method is defined in the Object class, which means you do not have to extend any class in order to use the toString() in your class. Stream operations are divided into intermediate and terminal operations and are combined to form stream pipelines.
