Spring Java Config: how do you create a prototype-scoped @Bean with runtime arguments?
...mic Parameter Two
com.spring3demo.account.service.TransferServiceImpl@70bde4a2
So the 'Singleton' Bean is requested twice. However as we would expect, Spring only creates it once. The second time it sees that it has that bean and just returns the existing object. The constructor (@Bean method) ...

Note the memory addresses of the lambdas - they are all different!
You could of course have a more "optimal" (haha) version of this expression:

Fixed point vs Floating point number
...of precision, so a value of 100 means actually means 1.00, 101 means 1.01, 12345 means 123.45, etc.
Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to have extra storage for where the...
How to convert String to long in Java?
...g -> Long, Long.valueOf(primitiveLong). So Long number = Long.valueOf("123"), Long number = Long.parseLong("123") and Long number = Long.valueOf(Long.parseString("123") all end up doing pretty much the same thing. What you do want to be careful about is not calling constructors of the boxed pri...

Why should I use Hamcrest-Matcher and assertThat() instead of traditional assertXXX()-Methods
...w advantages over hamcrest such as:
they are more readable
(assertEquals(123, actual); // reads "assert equals 123 is actual" vs
assertThat(actual).isEqualTo(123); // reads "assert that actual is equal to 123")
they are discoverable (you can make autocompletion work with any IDE).
Some examples

Different between parseInt() and valueOf() in java?
...ould also use this eyesore:
Integer k = Integer.valueOf(Integer.parseInt("123"))
Now, if what you want is the object and not the primitive, then using valueOf(String) may be more attractive than making a new object out of parseInt(String) because the former is consistently present across Integer,...

...xample that captures every key I could find on the keyboard:
var string = '123abcABC-_*(!@#$%^&*()_-={}[]:\"<>,.?/~`';
var stripped = string.replace(/[^A-Za-z0-9]/g, '');
console.log(stripped);
Outputs: '123abcABC'.
