    Default Instantiation troubles

    I have this variable of type PreciseTime that I need to instantiate to get it into a class called PhoneCall. here's the PhoneCall object signature [PhoneCall(PreciseTime, Precise Time).

    With that said I need to create a precise time object first before instantiating my PhoneCall.

    My user input variable is startIn. I have a method in PreciseTime called PreciseTime fromString(String).

    What am I missing to create my PreciseTime object

    PreciseTime callStart = new PreciseTime(startIn.fromString());

    Here is the compile error I get.
    CallCost.java:48: cannot find symbol
    symbol : method fromString()
    location: class java.lang.String
    PreciseTime callStart = new PreciseTime(startIn.fromString());
    ^
    CallCost.java:48: internal error; cannot instantiate PreciseTime.<init> at PreciseTime to ()
    PreciseTime callStart = new PreciseTime(startIn.fromString());

    Question 2:
    I need to write my PhoneCall object called phoneCall to a custom made string method. The call to the string is inside class PhoneCall. The toString() should call another toString() method inside another class. I want to make the one call and have it cascade to the other classes.

    main -- printOut.write(phoneCall.toString());
    PhoneCall class -- String startTimeOutput = startTime.toString(); startTime is a PreciseTime object and an instance variable in this class
    PreciseTime class -- return twentyFourHrTime; String toString(PreciseTime o) is the method and as you can see, accepts a PreciseTime object.

    What is wrong with the call from main? Below are the error messages.

    CallCost.java:65: write(java.lang.String) has private access in java.io.PrintStream
    printOut.write(phoneCall.toString());

    THANK YOU!

    Default Re: Instantiation troubles

    CallCost.java:48: cannot find symbol
    symbol : method fromString()
    location: class java.lang.String
    PreciseTime callStart = new PreciseTime(startIn.fromString());
    What class is startIn? Does it have a method: fromString()

    CallCost.java:65: write(java.lang.String) has private access in java.io.PrintStream
    printOut.write(phoneCall.toString());
    What class is printOut? The error message says the write(String) method is private.

    You need to post the code that defines all the variables shown in the error messages.
