Why you should care

[/vc_column_text][vc_column_text]Because the equals method takes a generic Object as a parameter, any type of object may be passed to it. The method should not assume it will only be used to test objects of its class type. It must instead check the parameter’s type.

CAST Highlight considers that the type of the parameter will be checked if the Equals method contains a “if” statement whose condition is checking <p>.getClass(), where <p> is the name of the parameter.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time an Equals method doesn’t test its parameter type using if + <p>.getClass().

Bad Code

class myClass {
equals(Object c) {
// no if (c.getGlass() ....) check ...
}
}

Good Code

class myClass {
equals(Object c) {
if (c.getClass() eq "myClass") {
...
}
...
}
}
