Define a Procfile

Use a Procfile, a text file in the root directory of your application, to explicitly declare what command should be executed to start your app. The Procfile in the example app you deployed looks like this: web: npm start. This declares a single process type, web , and the command needed to run it.

Why "F" and "L" suffix | (10.0F, 10L)

Let us take it this way, We will create their needs. So we will get why they are needed. Try to guess, which functions will be executed in the following program: public class MyClass { public static void main(String args[]) { MyClass obj = new MyClass(); obj.fun1(10); } void fun1(byte val){ System.out.println(val); } void fun1(int val){ System.out.println(val); } void fun1(float val){ System.out.println(val); } void fun1(long val){ System.out.println(val); } } It seems like every method is capable to run this program because 10 is still literal because It has no data type. Before Java, In previous technologies, this scenario gave an ambiguity...

Precedence and Associativity of Java operators

Precedence is the order to solve the operators. For simplicity, let's see the table Operator (Higher to Lower Precedence) Operators Precedence postfix expr ++ expr -- unary ++ expr -- expr + expr - expr ~ ! multiplicative * / % additive + - shift << >> >>> relational < > <= >= instanceof equality == != bitwise AND & bitwise exclusive OR ^ bitwise inclusive OR | logical AND && logical OR || ternary ? : assignment = += -= *= /= %= &= ^= |= <<= >>= >>>= Now, If we take an example and try to solve an expression, There can be a case of operators with the same precedence . ex. 10 * 20 / 4 % 2 When operators of equal precedence appear in the same expression, a rule must govern which is evaluated first. Now we use their Associativity. There is two kind of Associativity: Left to Right Right to Left For Unary Operators: Except the pos...
