When do you need to use this command: javac -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar *.java instead of javac *.java?

• always use the first command no matter what

• Use the first command when compiling junit tests

• always use the second command no matter what

java -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore testing

• it doesn't give an error

• should be this command

  java -cp ".;lib/junit-4.13.2.jar;lib/hamcrest-core-1.3.jar" org.junit.runner.JUnitCore testing

• missing .java at the end(testing.java)

• wrong path: missing lib folder
