Thanks, but can we write this to convert a string such as "asu" to integer

int x = br.read();
int y=br.read();
int z=br.read();

System.out.println(x+y+z);

Please do reply me.

I would be really gratefull to you if you could tell me the point which i am missing.

even if you write Integer.parsrInt("asu"); you will get Number format exception but if you write Integer.parseInt("197") it will give the number 197.

but i have tested every post on my netbeans ide it does not work.
The code which i have posted has been tested and verified on my ide and it does convert "asu" to 97.

if it is only "ee" then use

String s=firstString.substring(8,10);
System.out.println(s);

it will give the output "ee"
but if you would want any arbitary substring then your opinion is...

String s ="aabbccddeeffgg";
String s1=s.substring(4,7);
System.out.println(s1);

output=ccd

try using the following code it will surely work.

String s = "aabbccddeeffgg";
String s1 = s.substring(4,7);
System.out.println(s1);

it will give the output ccd.

use the substring method like this
String name = "fred blogs";
String FirstName = name.substring(0,4);
String LastName = name.substring(5,9);
System.out.println("Firstname"+Firstname+"...

Why JVM is platform dependent?

the main point is that we are assigning the default value to the boolean variable removedNodes so that when the program executes and there are any removed nodes then this var will be set to true...
