Ritika Singh Custom controller and VFP
A developer creates a customer controller and custom Visualforce page by using the following code block:
public class myController { public String myString;
public String getMyString() { return 'getMyString';
}
public String getStringMethod1() { return myString;
}
public String getStringMethod2() { if (myString == null)
myString = 'Method2'; return myString;
}
}
<apex:page controller="myController">
{!myString}, {!StringMethod1}, {!StringMethod2}, {!myString}
</apex:page>
What does the user see when accessing the custom page?
a. getMysString, , Method2, getMyString
b. , , Method2, getMyString
c. , , Method2,
d. getMyString, , ,
public class myController { public String myString;
public String getMyString() { return 'getMyString';
}
public String getStringMethod1() { return myString;
}
public String getStringMethod2() { if (myString == null)
myString = 'Method2'; return myString;
}
}
<apex:page controller="myController">
{!myString}, {!StringMethod1}, {!StringMethod2}, {!myString}
</apex:page>
What does the user see when accessing the custom page?
a. getMysString, , Method2, getMyString
b. , , Method2, getMyString
c. , , Method2,
d. getMyString, , ,
The answer is :
a. getMyString, , Method2, getMyString
As first when you called
{!myString} : getMyString() is called and value is 'getMyString'.
{!StringMethod1} : it calls getStringMethod1() and value is blank or ''.
{!StringMethod2} : it calls getStringMethod2() and value is 'Method2'.
{!myString} : getMyString() is called and value is 'getMyString'.
Do let me know if it helps you and close your query by marking it as solved.
