Variables can be defined at any point in a block, and take on scope from that point forward. Sub-blocks can’t redefine a variable name that has already been used in a parent block, but parallel blocks can reuse a variable name.
What is a string in the apex program?
String is any set of characters within single quotes. It does not have any limit for the number of characters. Here, the heap size will be used to determine the number of characters.
