, an error is given. For example, Java is a static language, and assignment statements are as follows (//for comments): int a = 123; A is an integer type variable a = "ABC"; Error: Cannot assign string to integer variable This is why dynamic languages are more flexible than static languages. Do not equate an equal sign of an assignment statement with a mathematical equal sign. For example, the following code: x = 10x = x + 2 If mathematically understood x = x + 2 that is not true anyway, in the

Why do you specialize in opening a pit to use pb.
