In one of the previous lessons, we covered conversion from String to int. Here, you will learn how to convert int to String in Java. There are some predefined methods that we can use for that, like the following:
- String.valueOf() method
- Integer.toString method
- String.format() method
Convert int to String in Java using the String.valueOf() method
There are multiple overloaded versions of the valueOf() method from the String class. We will use the one which accepts int as an argument.
Example
class Test {
public static void main(String[] args) {
String str = String.valueOf(32);
System.out.println(str);
}
}
Output: 32
Convert int to String using the Integer.toString() method
We can also use the static method toString() of the Integer class. It returns a String representation of a provided int.
class Test {
public static void main(String[] args) {
String str = Integer.toString(82);
System.out.println(str);
}
}
Output: 82
Parse int to String using the String.format() method
The String.format() method returns a formatted String based on the arguments.
Example
class Test {
public static void main(String[] args) {
int num = 501;
String str = String.format("%d", num);
System.out.println(str);
}
}
Output: 501
Note: The %d specifies that the single variable is a decimal integer.
That’s it!
