2 Basic Questions from a beginner! -Java + iReport

[petermere]

1. In Java I have:

Class A {

private B b;

private int field 1;

}

Class B {

private int field 2;

private int field 3;

}

 

In my jrmx file, how can I access field 2 and field 3, having a list of A object.

 

2. In iReport, how can I distribute the columns evenly.

For example, I have:

FirstName Name Telephone.

I want all these 3 columns to have the same width.

You can't.  A's reference to its B is private.  See the attached code.

 

 

Code:

File Test.java:import java.util.Arrays;import java.util.List;class A {    private B b;    private int field1;}class B {    private int field2;    private int field3;}public class Test {    void foo() {        List<A> list = Arrays.asList(new A());        A a = list.get(0);        int n = a.b.field2;    }}>javac Test.javaTest.java:19: b has private access in A        int n = a.b.field2;                 ^Test.java:19: field2 has private access in B        int n = a.b.field2;                   ^2 errors
