-
Guest.java
-
private Integer _Id;

public Integer getId()
{
return _Id;
}

public void setId(Integer pId)
{
_Id = pId;
}

-
a.java
-
String strGuestID = "";
String GuestID = "";

GuestID = strGuestID.substring(0, 4);

The GuestID is get from the text file, so GuestID is String. Now, i would like to set the GuestID in Guest.java. The problem is the GuestID in a.java is String but in Guest.java is Integer, so may i know how to convert String to Integer in java?

If you actually want to create an Integer object from a string (i.e. an object of class Integer, rather than a normal int), then you can use the Integer constructor that takes a string:

Integer i = new Integer("2");

If you just want to get the integer from the string into a "normal" int variable, then use the parseInt method of the Integer class:

int i = Integer.parseInt("2");

GuestID = Integer.toString(Id);

converts integer to string
