I have a very good buddy of mind that I would love for you to meet... His name is JSON.

He's lightweight, and surprisingly useful for many many unexpected ways such as this preticular situation.

JSON is the kind of man whos got your back, when your cornered by knife wielding crusted gutter punks looking to skin you alive. You think to yourself... This must be the end of for us. JSON reaches into his trench coat for a fresh dart, and ignites it with his limited edition phub themed zippo. JSON inhales a very deep drag, and then suddenly hunches over starts coughing out of control. JSON slowly turns his head towards you and says " Oh yeah, I forgot... I don't even smoke".

we can use wrapper classes to convert String to int
for example :
String s ="6789";
int num = Integer. parseInt(s) ;
System. out. print(num) ;
output: 6789
