![]() ![]() For example, it starts by constructing a StringBuilder object, then appending the integer, and finally, it calls the toString() method on the number. Then, it invokes a series of function calls to complete the process in Java. The process is relatively straightforward you start by adding an empty string value to your number, similar to JavaScript typecasting. However, in the case of data types, it works very well to convert into strings. It is important to note that it may behave unpredictably with certain types of numbers. The concatenation technique is the last way to convert int to a string that this post will cover. Java Convert Int to String Using Concatenation When combined, the two symbols tell the compiler that it can accept any combination of numbers so long as they are of the type int or integer. The first symbol is the percentage symbol which indicates any pattern is acceptable, and the second symbol dictates what type of data it should be converting. For example, in the case of converting a number of int or integer types, you would need to pass in two symbols. Since this method can convert many different types of data into strings, it comes with several formatting options. This syntax is again similar to the above methods, with the one difference being the formatting parameter. Let’s look at the syntax for this method next. It first requires a pattern that determines the format the string should be returned in, and the second parameter is the number in the form of an int or integer. The most significant difference with this method is that it needs two parameters passed to work. Like the above two methods, you can call the class name and chain the method you want to utilize. Java Convert String Using the Format MethodĪnother way to convert int data types to strings is to use the format() method, which belongs to the String class. Like the toString() method, you start by calling the class it’s from - in this case, it is the String class - then you chain the method you want to utilize and pass it a number to convert. The following code example showcases the syntax for the valueOf() method. The valueOf() method originates from the String Class and returns the value of an integer in a string format. Next is the valueOf() method from the Java String Class, which accepts a number value and converts it into a string. Java Convert Int to String Using the ValueOf Method In most cases, developers pass in a dynamically defined variable or value. The function - or method - will accept a number and convert it into a string. It refers to the Integer class and calls its static function toString(). The above line of code is simple to break down. For example, the Integer class in Java has a static function named toString() that changes a given integer into a string. It serves to convert different types of data to a string data type. Java Convert Int to String Using the ToString Method This next video shows how to convert int to string and explains why it is a helpful task to perform. Some other methods and techniques can perform this function, too let’s look at those next. One way is to use the toString() method - arguably the most commonly used - of which a variant can be found in many Java Classes. There are a few ways to perform conversions in Java, changing integers into strings for various purposes. Next, let’s go over the different techniques you can use to perform integer conversions and how they differ from each other. So far, you’ve learned about what int to string conversion is and why it is essential. This is just one of many limitations developers can face when working with integers, hence the benefit of int to string conversion. After conversion you can use other methods to iterate through the string using for loops, or while loops. To accomplish iterating over a number - say to find a specific set of numbers - you would need to convert the integer to a string. A great example is iterating over a character, which cannot be performed on integer data types. ![]() In addition, string data is more flexible to work with because the string class has more methods.įurthermore, there are other classes and methods than can be used to interact with strings since it is a prevalent data type. However, it is also beneficial for accessing and manipulating numerical data. ![]() Whereas valueOf() returns Integer object.Converting integers into strings is helpful for a multitude of different tasks, especially common for displaying data to users in a readable format. It must be noticed that parseInt() returns a primitive int type. ![]() On another hand valueOf() accepts both Strings and Integers. The key difference is that parseInt() takes in only String as input. Addressing the problem straight away, we have two ways to work with. Converting object to int is a simple work in Java. ![]()
