Second day At Noida: Learning some crucial concepts of java

-
Hello Readers! Today was my another day in Apex Pvt Ltd. I have explored today some basic commands in java as "JavaP" 

 I have also learnt how we can view all the functions of a class so that we come to know how we will use another class with the shown function of an existing class.

 I have mentioned some examples of JavaP command in cmd prompt:

 Follow the instruction if you want to use javap cmd:
  • First of all, compile your java file using javac.
  • then write javap followed by your class name.
  • you will get the functions used in that class. 
check out the picture mentioned below:


For using this cmd, we will be familiar with the functions of a class without opening that.
