Move your print command to the wrong part of the program Ive just started learning Java (I am a C.NET programmer as well).Run the code each time and read the compiler’s error messages. “Break” your code in a few different ways to see what sort of error message you get.For example, make it say “This is my first program.” and then a new line to print “Learning to program takes a lot of work, but it is worth it!” (each of these command ends with a semicolon ) The BlueJ integrated development environment is highly interactive and encourages experimentation and exploration. Add more code so your program will print multiple statements when you run it.Lines of code between curly braces make up a code block. BlueJ purpose is to spread education and it helps. ![]() BlueJ is an IDE-Integrated Development Environment for beginners.
