Whenever I rung my code and add an argument, for this case Rectangle, it will give me a java.io.FileNotFoundException: Rectangle (The system cannot find the file specified) at java.base/java.io.FileInputStream.open0(Native Method) at java.base/java.io.FileInputStream.open(FileInputStream.java:211) at java.base/java.io.FileInputStream.(FileInputStream.java:153) at java.base/java.util.Scanner.(Scanner.java:639) at Project3.main(Project3.java:135) What can I do to fix this? here is my code
