Public: For those methods that are necessary to use an object. Note that attributes should never be public. If other objects need access to attributes, create getters and declare them as final. Protected: Best reserved specifically for subclass use. I do not declare anything as protected unless...
Setters and Getters of JavaBeans in Java Here, we are using setters methods to set values and then getter methods to get values. This is the strength of JavaBeans. See the example below. publicclassMain{publicstaticvoidmain(String[]args){SimpleTesting st=newSimpleTesting();st.setId(1);...
