How to convert an int to a String in Java
In this section, we will show you how to convert an int to a String in Java.
Following ways can be used for converting int to String:
1. By using Integer.toString() method
2. By using String.valueOf() method
Note: Integer.toString() method is faster than String.valueOf(). String.valueOf() method internally invokes the Integer.toString() method.
public static String valueOf(int i) {
return Integer.toString(i);
}
Note: Integer.toString() method is faster than String.valueOf(). String.valueOf() method internally invokes the Integer.toString() method.
public static String valueOf(int i) {
return Integer.toString(i);
}Example 1: Using Integer.toString() method
The java.lang.Integer.toString() is an inbuilt method in Java which is used to returns the string object of the particular Integer value. By default, the argument is converted to signed decimal (radix 10) in string format.
public class Main {
// Driver code
public static void main(String[] args)
{
int val = 9;
String str = Integer.toString(val);
System.out.println("String => "+str);
}
}
String => 9Example 2: Using String.valueOf()
The java.lang.String.valueOf(int i) returns the string representation of the int argument. It internally invokes the Integer.toString() so the representations are always exactly the same.
public class Main {
// Driver code
public static void main(String[] args)
{
int val = 9;
String str = String.valueOf(val);
System.out.println("String => "+str);
}
}
Console Output:String => 9
String => 9
