Overview

Enhance your coding interview skills with this Java course path. Start with foundational exercises, tackle classic coding questions, and master complex algorithms. Learn string manipulation, list operations, recursion, linked lists, dynamic programming, and graph algorithms to excel in interviews.

What you'll learn

  • Solve common coding interview problems using Java
  • Manipulate strings, arrays, lists, and matrices
  • Implement linked lists, binary trees, hash tables, and heaps
  • Apply recursion and dynamic programming to algorithmic problems
  • Use graph algorithms to solve complex traversal and optimization tasks
  • Implement string searching and bit manipulation techniques
  • Evaluate and improve the efficiency of interview solutions

Advantages and disadvantages

Advantages

  • University courses you can audit for free, with lectures, readings and practice quizzes.
  • A verified certificate from the university if you pay for it.
  • Self-paced: start any time.

Disadvantages

  • Graded assignments and the certificate need the paid track.
  • Audit access can expire a few weeks after the course ends.
  • Learning is free, but the certificate costs money.
