How to convert string and INT in Java

 1. Convert string to int

There are two methods:

1). Int I = integer. parseint ([String]); or I = integer. parseint ([String], [int Radix]);

Here I = integer. parseint ([String], [int Radix])

For example:

String STR = "123 ",
Int I = integer. parseint (STR, 8 ),
The following parameter indicates the value obtained by. I when STR is regarded as the number of hexadecimal notation (I is a 10 hexadecimal notation)
For example, I = integer. parseint (STR, 5). I = 38. Indicates 1*5*5 + 2*5 + 3.

2). Int I = integer. valueof (my_str). intvalue ();
 

2. Convert int to string

There are three methods:

1.) string S = string. valueof (I );

2.) string S = integer. tostring (I );

3.) string S = "" + I;
