Garbage collection ..

[manal]

Consider the following program :::
public class Manal {
static int m;
public int met() {
return this.m;
}
public Manal() {Manal.m ++ ;}
public static void main(String s []) {
for(int lp = 0; lp< 100;lp++)
System.out.println(new Manal().met());
System.out.println("the no. of objects created r " + m);
}
}
can any1 pls tell me hw many objects r eligible for garbage collection when this program exit ...
i think 203 bcos ::
100 objects of Manal class
100 String objects from System.out.println(new Manal().met());
2 String objects ("the no. of objects created r " and other is toString(m) )
& 1 String frm System.out.println("the no. of objects created r " + m)
what do u say ....

I say there are just 201 objects created.
coz : "something" + m - does not create 3 objects. It just creates one objects.
Heres the explanation :
String buffers are used by the compiler to implement the binary string concatenation operator . For example, the code:

x = "a" + 4 + "c"

is compiled to the equivalent of:

x = new StringBuffer().append("a").append(4).append("c")
.toString()

which creates a new string buffer (initially empty), appends the string representation of each operand to the string buffer in turn, and then converts the contents of the string buffer to a string. Overall, this avoids creating many temporary strings.
