In java, all the variables needs to be declared first i.e. before using a particular variable, it must be declared in the program for the memory allocation process. Like
int pedal = 1;
This statement exists a field named "pedal" that holds the numerical value as 1. The value assigned to a variable determines its data type, on which the legal operations of java are performed. This behavior specifies that, Java is a strongly-typed programming language.
