How to convert String to Integer and Integer to String in java

Following is the program to demonstrate it.

File: ConvertStringToInteger.java

public class ConvertStringToInteger {
	public static void main(String[] args) {
	    //1st way
		String str1 = "5";
		int result = Integer.parseInt(str1); // Using Integer.parsrInt()
		System.out.println(result);
 
        //2nd way
		String str2 = "5";
		Integer result2 = Integer.valueOf(str2); // Using Integer.valueOf()
		System.out.println(result2);
 
	}
}

Output:

5
5

File: ConvertIntegerToString.java

public class ConvertIntegerToString{
	public static void main(String[] args) {
 
		int x = 5;
		//1st way
		String str = Integer.toString(x); // using Integer.toString()
		System.out.println(str);
 
        //2nd way
        String str2 = String.valueOf(x); // using String.valueOf()
		System.out.println(str2);

	}
}

Output:
