![]() ![]() This application code retrieves a string: This layout XML applies a string to a View: example: XML file saved at res/values/strings.xml: For more information about how to properly style and format your strings see Formatting and Styling, below.Īttributes: name String. Beware that you must escape apostrophes and A string, which can include styling tags. compiled resource datatype: Resource pointer to a String. So, you canĬombine string resources with other simple resources in the one XML file, Using the value provided in the name attribute (not the name of the XML file). Note: A string is a simple resource that is referenced StringĪ single string that can be referenced from the application or from other resource files (such Information about styling and formatting strings, see the section about Formatting and Styling. Quantity Strings (Plurals) XML resource that carries different strings for pluralization.Īll strings are capable of applying some styling markup and formatting arguments. String Array XML resource that provides an array of strings. Your application with strings: String XML resource that provides a single string. There are three types of resources that can provide With optional text styling and formatting. In the next tutorial, we will learn how to convert long numeric value to a string in Java.A string resource provides text strings for your application Hope that you will have understood the basic methods of converting a string into a long. In this tutorial, you learned how to convert a string to long numeric value in Java using the following ways easily. (str + " is not a valid numeric value.") Long num = decimalFormat.parse(str).longValue() Create an object of DecimalFormat class.ĭecimalFormat decimalFormat = new DecimalFormat("#") Program code 4: // Java Program to demonstrate the conversion of String into long using DecimalFormat class. ![]() Let’s create a Java program to convert a string to long numeric value using DecimalFormat class. We can also use in other way to parse a string into its numerical representation. This class is present in java.text package. ![]() Java provides a class called DecimalFormat that allows to convert a number to its string representation. Program code 3: // Java program to convert a string into a long using new Long(String).longValue().Ĭonverting String to Long using DecimalFormat Let’s create a Java program to convert String into a long object using longValue() method. Unboxing is a process by which we convert an object into its corresponding primitive data type. The longValue() method converts the long object into primitive long type value. Program code 2: // Java program to convert a string into a primitive long type using valueOf() method.Ĭonverting String to Long using new Long(String).longValue()Īnother alternative approach is to create an instance of Long class and then call longValue() method of Long class. Let’s write a Java program to convert a string into a long value using valueOf() method of Java Long wrapper class. We can invoke it using its class name.The general signature of valueOf() method is as below: public static Long valueOf(String str) It is a static utility method, so we do not need to create an object of class. The valueOf() method of Long class converts a string containing a long number into Long object and returns that object. We can also convert a string to long numeric value using valueOf() of Java long wrapper class. ![]() Call parseLong() method to convert a string to long value.Ĭonverting String to Long in Java using Long.valueOf() Program code 1: // Java program to convert a string into a primitive long type using parseLong() method. Let’s create a Java program to convert string to long in java using parseLong() of Java Long class. The parseLong() method throws an exception named NumberFormatException if the string does not contain a parsable long value. This method accepts a string containing the long representation to be parsed. The general signature of parseLong() method is as below: public static long parseLong(String s) We can call it simply using its class name. So, we do not need to create an object of class to call it. It reads long numeric values from the command-line arguments. The parseLong() of Long class is the static method. To convert string to a long, we use Long.parseLong() method provided by the Long class. Converting String to Long in Java using Long.parseLong() ![]()
