String replacement in java, similar to a velocity template

Closed 4 years ago.
I need to augment some string like it's done by logback/famous loggers or property accessors.
String str= "I can {0} give {1} back your horses or restore your {2} to life.";
String[] got=new String[]{"not","you","dead"};
Are they any utility functions provided by any library that can convert str to replace {i} with indices in array?
Its most probably a duplicate and please refer me to some similar question.

I have only idea with loop. It works but it doesn't looks elegant. Maybe somebody can advice more easy way to do it?
Try to use String.join("; ", list)
It should work

Is there any way to join a string and another variable together, that is also a string, without using the "+" operator. Specifically one similar to this one that is done in C#.
string str = $"Hello {userName}. Today is {date}.";
If there is any way to achieve a similar or same outcome in Java please let me know.
See https://docs.oracle.com/javase/7/docs/api/java/lang/String.html
String.format("Hello %s. Today is %s.", userName, date);

I do not understand what the difference between
int Hello ;
and

is .
Does it make a big difference if i use upper case Characters ?
That's because of Java Convention!
Actually, you can write a program like the way you're imagining but, you won't be following any pattern.......If you become a real programmer someday, you'll understand that patterns exist to make things better and easier.....

I have a equation in string format like "45+5*4-6" which I have to solve in Java.
Is there any way to solve equation which is in string format?
Check Beanshell
Something like this should work -
Interpreter ip = new Interpreter();
ip.eval("res = 45+5*4-6");
System.out.print(ip.get("res"));
