In java first all the integer or float etc declared are
converted into string so when we write
System.out.println("the name is"+x);where x is any primitive
type then first x is converted into string then it
concatenates with the other string so for concatenations
with other string we must have +operator.
class xyz{
static int x;
public static void main(String args[]){
xyz yz=new xyz();
yz.x=10;
System.out.println("the output is"+x);//here concat done
}
}
