How do I master debug?

What are the four steps to debugging?

Identify. Identify is the first step in the debugging, it means discover what is the bug and why it happen.
Isolate. Isolate is a step to separate the buggy code with other healthy code; I usually make an Unit Test referencing that part of code and then reproduce the bug using that unit test;
Fix.
Review.
Conclusion.

What does F5 does during debugging?

1.5. Controlling the program execution

Key	Description
F5	Executes the currently selected line and goes to the next line in your program. If the selected line is a method call the debugger steps into the associated code.
F6	F6 steps over the call, i.e. it executes a method without stepping into it in the debugger.

What is meant by debugger?

A debugger is a computer program used by programmers to test and debug a target program. Debuggers may use instruction-set simulators, rather than running a program directly on the processor to achieve a higher level of control over its execution. They also can often modify the state of programs while they are running.

Is debugging safe?

USB debugging is basically a way for an Android device to communicate with the Android SDK over a USB connection.

Which is a debugging tool?

Which language is easiest debugging?

Java is a statically typed and compiled language, and Python is a dynamically typed and interpreted language. This single difference makes Java faster at runtime and easier to debug, but Python is easier to use and easier to read.
