Why does this go into an infinite loop?
... perform the operation. There is also another data structure, typically an array to store the local variables. The local variables are given ids which are just the indexes to the array.
Let us look at the mnemonics in main() method:
iconst_0: The constant value 0
is pushed on to the stack.

Should I use Java's String.format() if performance is important?
... the format chunks, rendering into a StringBuilder, which is basically an array that resizes itself as necessary, by copying into a new array. this is necessary because we don't yet know how large to allocate the final String
StringBuilder.toString() copies his internal buffer into a new String

How to find all positions of the maximum value in a list?
...
You can also use the numpy package:
import numpy as np
A = np.array(a)
maximum_indices = np.where(A==max(a))
This will return an numpy array of all the indices that contain the max value
if you want to turn this to a list:
maximum_indices_list = maximum_indices.tolist()

How to convert a String to its equivalent LINQ Expression Tree?
...icular, I'm thinking as a Where clause. If necessary, put it inside a list/array just to call .Where(string) on it! i.e.

What is the Java string pool and how is “s” different from new String(“s”)? [duplicate]
... In most cases (when the size of the String and the underlying char array are equal), the new String object will have the same underlying char array as the passed String object. So there is one copy of 'abc' in memory (represented as a char array), but two strings using this.
