Answer 2

There are at least three ways to do it. Two have already been pointed out:

String s = String.valueOf(i);

String s = Integer.toString(i);

Another more concise way is:

String s = "" + i;

See it working online: ideone

This is particularly useful if the reason you are converting the integer to a string is in order to concatenate it to another string, as it means you can omit the explicit conversion:

System.out.println("The value of i is: " + i);

Answer 3

  Integer yourInt;
  yourInt = 3;
  String yourString = yourInt.toString();

Answer 4

you can either use

String.valueOf(intVarable)

or

Integer.toString(intVarable)

Answer 5

There are many different type of wat to convert Integer value to string

 // for example i =10

  1) String.valueOf(i);//Now it will return "10"  

  2 String s=Integer.toString(i);//Now it will return "10" 

  3) StringBuilder string = string.append(i).toString();

   //i = any integer nuber

  4) String string = "" + i; 

  5)  StringBuilder string = string.append(i).toString();

  6) String million = String.format("%d", 1000000)
