Break and continue are two important keywords used in loops. When using abreakkeyword in a loop, the loop breaks instantly. The current iteration breaks when using thecontinuekeyword, and the loop continues with the next iteration. Java string interview questions What is the entry point in Java...
hence lack of subject understanding can land you in trouble. Java starts with basic concepts such as conditional statements, loops and applications and go all the way to threads, ports, design patterns. Hence, you should either start early in your java coursework or be prepared to hire an onl...
