In JAVA programming it is very frequent demand of converting an int/Integer to String.

Below snapshot shows how this is done. Easy to remember.

public class DataTypeCoversionDemo {
            private static String strVar = "11";
            private static int intVar = 22;
            private static Integer integerVar = 222;
     
      public static void main(String[] args) {      
          convertInt_String();   
      }

      public static void convertInt_String(){
            // ********* Integer to int ********** //
            Integer tInteger = Integer.valueOf(intVar);
            int tSimpleIntValue = tInteger.intValue();

            System.out.println("Simple Int to Integer  :- " + tInteger); //22      
            System.out.println("Integer to Simple int :- " + tSimpleIntValue); //22

            // ********* int to String ********* //
            String tString = String.valueOf(intVar);
            int tInt = Integer.parseInt(strVar);

            System.out.println("Simple Int to String :- " + tString); //22
            System.out.println("String to Simple Int :- " + tInt); //11

            // ******* Integer to String ******* //  
            String tString2 = integerVar.toString();
            Integer tInteger2 = Integer.parseInt(strVar);        

            System.out.println("Integer to String :- " + tString2); //222
            System.out.println("String to Integer :- " + tInteger2); //11
      }
}
