Java – understand the “symbol not found” error
•
Java
What is this mistake?
cannot find symbol,symbol: method getstring(java.lang.String)
Location: class InternalFrameDemo
if <!windowTitleField.getText().equals(getstring("InternalFrameDemo.frame_label")))
Solution
Java is case sensitive Because "getString" is not equal to "getString", the compiler considers that there is no "getString" method in the internalframedemo class and throws the error
In Java, methods usually have the first letter of each word after the first word is capitalized (e.g. tostring(), touppercase(), etc.), the class will use upper camel case (e.g. classname, string, StringBuilder), and the constant will be at the full upper limit (e.g. max_value)
