Learn to convert int to String in Java? Techniques and methods such as toString, valueOf, etc convert int to stringFor converting int to string java, we must understand the two data types and how to interchange them.int to String ConversionSimply speaking, int data type stores numbers from –2,147,483,648 to 2,147,483,647.Whereas, String contains a set of characters also known as char in Java. The int is a primitive data type in Java.Unlike int, String is a pre-defined class and every word that we create using String class is treated as an Object.Data typeSizeDescriptionbyte1 byteStores whole number from -128 to 127short2 byteStores whole number from -32,768 to 32,767short2 byteStores whole number from -32,768 to 32,767int4 bytesStores whole number from -2,147,483,648 to 2,147,483,647long8 bytesStores whole number from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807float4 bytesStores fractional number. Sufficient for storing 6 to 7 decimal digitsdouble8 bytesStores fractional number. Sufficient for storing 15 decimal digitsboolean1 bitStores true or falsechar2 bytesStores a single character/letter or ASCII valuesThere are a number of ways to convert an int to String in JavaLet’s take a tour.Firstly, Using toString: Integer.toString(Integer i)Second, Using concatenation: ‘int i’+”;Using valueOf: String.valueOf(Integer i)Using StringBuffer/ StringBuilder: builderObject.apend(Integer i) methodFinally, Using String format: String.format(“%d”,’int i’);Before we dive in, you should know that just like int we also have an Integer class in Java. They are both meant to store ‘numbers’ or ‘integers’ BUT int is a primitive data type whereas Integer is a wrapper class for int.The primary advantage of Wrapper Classes is that we need Wrapper objects to function with collections which are only possible with the help of Wrapper classes. As the wrapper classes have objects we can store null as a value.We could not store null in variables of primitive datatype.In all these methods we have used int i to be converted to String but the same could be achieved using Integer i. [syntax: Integer i = new Integer(1);]toString method to change int to to StringA toString() is an in-built method in Java that returns the value given to it in string format. Hence, we can also use it to convert an int value to a String.We call the toString method from the Integer class as shown below.public class IntToStringDemo { public static void main(String[] args) { int i = 1; String s = Integer.toString(i); System.out.println(“Java int “+i+” to String “+s+””””)
