Long value of input string is -999999999 Conclusion This method parses the string as a signed decimal long, and returns the resulting long value. Short solution: The best way to convert binary String to long in java is to use Long.parseLong() method. If you visit the official documentation of the Java Long class then you will find that the long class has a constructor which allows the String argument and creates a new Long object representing the specified string in the equivalent long value.īelow is the example for conversion of string to long by using the constructor of the Long class. To convert a string to a long in Java, you can use the parseLong () method of the class. One of the ways to convert string to long is by using the constructor of the Long class. Long value of input string is -999999111 3. ("Long value of input string is " + valueInLong) The Long.valueOf() method works the same as parseLong and this also allows the first character of the string as a digit or minus sign ‘-‘.īelow is the program to convert string to long in Java by using the Long.valueOf() method. ("Long value of input string is "+ valueInLong) We can pass any string( which contains digits only except the first digit, which can be a digit or a minus ‘-‘) to parse the long() method and this will return a long value corresponding to this.īelow is the program for the string to long conversion by using the parseLong() method of the Long class. The parseLong() is the method present inside the Long class. If our obj object is null, well get a NullPointerException. Use Long.parseLong() method to convert String to Long We can simply use the toString () method of the Long class to convert them to String: String str1 Long.toString (l) String str2 Long.toString (obj) (str1) (str2) The output will look like this: 10 15. Its value lies in the range of (-263) to (263 -1)(inclusive).īelow are the 3 different approaches to convert a string to long in Java. However, The long data type is a 64 bit two’s complement integer. String in Java is the object that is supported by the char array internally. ![]() Input: String = "100" īefore going to the 3 different ways for conversion of string to long in Java let’s take a simple introduction of String and Long. Below is the sample input and output for the program. In this tutorial, well explore several ways to convert String objects into Date objects.Well start with the new Date Time API, java.time, that was introduced in Java 8 before looking at the old data type also used for representing dates. We have a string, and our main task is to convert the given string to Long in Java. Therefore it seems to be treated as a string. The value of dxorderid is retrieved from a parameter in the URL of the page called. We will demonstrate 3 different ways for conversion of string to long in Java with the help of the programs. String dxorderId request.getParameter ('orderid') long orderid Long.parseLong ( (dxorderId)) It is inside a servlet which is called from a PL/SQL procedure. In this tutorial, we will learn one of the very common requirements in Java applications i.e. ![]()
