All are the ways, you can use any one. There is no any condition that you have to use 1 way in this condition like that. These are the 4 ways, suppose if you forget one way then you can use other ways. Thanks @sujoy
Hola, Buenos días. There are so many solutions, java 9 they have introduced some feature. but if you are using JDK 1.6 and greater than then use this ScriptEngineManager manager = new ScriptEngineManager(); ScriptEngine engine = manager.getEngineByName("js"); String question = "5+3*2"; System.out.println(engine.eval(question)); This is just a way, not a permanent solution. Check below stackoverflow.com/questions/3422673/how-to-evaluate-a-math-expression-given-in-string-form
hi, it is not necessary, but sometime you will have any data as a string but during some process you need the data as int, so on that time it need to be converted. It can be string to int,vice versa
just run for loop and use parseInt and store into new array. Example: String [] str = {"12", "34", "56"}; int size = str.length; int [] arr = new int [size]; for(int i=0; i
if you want the number as 33 and 55 seperately then try to use split method on the basis of space. so you will get two number at the index of 0 and 1. after that you can use. Please let me know if you have any questions

What's the difference among these 4 ways and which one to use when?

String s=String.valueOf(d);

How do I convert an array of strings into an array of integers?
just run for loop and use parseInt and store into new array.
Example:
String [] str = {"12", "34", "56"};
int size = str.length;
int [] arr = new int [size];
for(int i=0; i
Talented Developer Thanks for the quick response! That’s what I figured out. 😊
Most welcome.
Great, keep going on. 😀

What if I want variable in JSP to receive a value from an input text in HTML.?
Hi @Isaac, create a function that will convert string to int. That function call in input text in html.
or you can use parseint () in JavaScript also
What if my string is "33 55" so I have 2 numbers how can I get the tow numbers
if you want the number as 33 and 55 seperately then try to use split method on the basis of space.
so you will get two number at the index of 0 and 1.
after that you can use.
Please let me know if you have any questions
