Bug 227545

Summary: Error hint for incompatible types - change declaration
Product: java Reporter: markiewb
Component: HintsAssignee: Svata Dedic <sdedic>
Status: NEW ---    
Severity: normal    
Priority: P3    
Version: 7.3

Attachments: Shows the current state, only error hint "add cast"

Description markiewb 2013-03-16 07:03:43 UTC 
<code>
public class NewClass {

    Set var;
    
    public void method() {
	var=otherMethod(); // error is here so open quickfix
    }

    public Date otherMethod() {
	return new Date();
    }
}
</code>

The dev could solve the error by
* casting OR
* changing the declaration
But only a casting hint is shown

ACTUAL:
* fixable hint: cast ... to Set

EXPECTED:
* fixable hint: cast ... to Set 
* fixable hint: change declaration type of "var" to java.util.Date

Do you think the user expects that the result will be (again) uncompilable because otherMethod() declared return type does not match the method's body?

Sorry, Svata. I do not understand, what you mean. Here are the expected results

a) fixable hint: cast ... to Set 
<code>
public class NewClass {

    Set var;
    
    public void method() {
	var=(Set) otherMethod(); //fixed
    }

    public Date otherMethod() {
	return new Date();
    }
}
</code>

b) fixable hint: change declaration type of "var" to java.util.Date
<code>
public class NewClass {

    java.util.Date var;
    
    public void method() {
	var=otherMethod(); //fixed
    }

    public Date otherMethod() {
	return new Date();
    }
}
</code>
