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
}
}
