string + int

[javi cervera]

this code compile:
String s = "hello" + 7 ;
ok
but this compile also?
String s = 7 + "hello";
in my compiler yes, but i have read in certification books that this code not compile. What is the answer in the exam?

Thanks in advance.

yes. In both the cases, 7 will be converted into string and will be concatenated to hello

The Java compiler treats + as string concatenation if either operand is a String.

The order is important, though. See this sample code:

public class Test24
{
public static void main(String args[])
{
System.out.println(2 + 2 + " is four"); 
System.out.println("four is " + 2 + 2);  
}
}
