When given you a rotated sorted array, would you be able to find the minimum without going through all the elements? What about finding the maximum? Want to know more, then read on! Issac Chua 2 min read Java variable initialization and default values...
A variable has a type, which is specified when the variable is declared. A variable can only be assigned a value that is compatible with its type. Type incompatibilities are caught at compile time. All instance and class variables are given default values when they are declared. However, th...
Variable Initialization is the process of assigning an initial value to a variable in a computer program, typically done at the beginning of a loop or function.

One reason is that Java doesn’t support default arguments to provide the initialization values necessary for type inference. Type inference works nicely in for loops. Copy code snippet Copied to Clipboard Error: Could not Copy Copied to Clipboard Error: Could not Copy // housekeeping/ForType...
1.vardeclaration and initialization at the same time When usingvar, we must initialize the variable at the same place. We cannot put declaration and initialization at different places. If we do not initialize the variable in place, then we will get a compilation error –Cannot use 'var' on...

If you decompile bytecodes of a class, you’ll realize that a field (or instance variable) is initialized in a class constructor. So even if you initialize a field with its declaration, the compiler would move its initialization code to the constructor. Also, all the code in the instance...
