As you want to return both Integer and String, you can use return type as Object class, because Object is super class of all classes and we can hold any type of value in Object variable.

public static Object type(String s){    
    // code here
}

Now you can get the type of value return by type with the help of instanceOf method

if(Utils.type() instaceOf String)
{
    // code here
} else if(Utils.type() instanceOf Integer) {
    // code here
}

As User has suggested that you can return change method return type to object. But, apart from that you can also use either of

  1. String.valueOf(number) (my preference)
  2. Integer.toString(number)

to return integer as string and perform type check at method calling point
