Question

I am trying to wrap TestClass1[] in TestClass and for this I have created a TestClass. There is a method in another class FunctionClass which will return the array of the TestClass. I have defined some variables in Testclass one is String and the other one is a class TestClass2. I will wrap the TestClass2 in Testclass.

Testclass2 also has 2 variables, one is String and one is int. I want to know how can i construct an array of Testclass which should have the corresponding variables in it.

I have the following code.

public class Testclass {

private String attrName;
    private TestClass1 tc;
    private TestClass2 tc2;

Testclass(Testclass1[] tc1){

    for(int i=0; i<tc1.length; i++){
    tc = tc1[i];
    attrName = this.tc.name; 
    tc2 = new TestClass2 (this.tc.elements); //this.tc.elements will return an Array of SomeClass which is not implemented by me.
    }

}

/**
 * Returns the Name.
 */
public String getName()
{
    return attrName;
}

/**
 * Returns the Testclass2 Array
 */
public TestClass2[] getTestClass2(){

//What to do ??
}



 /**
 * Testclass2 which is inner class of TesTClass.
 */
 private class Testclass2 {

    private int value;
    private string attribute;
    private SomeClass some;

    TestClass2 (SomeClass[] someClass){

        for(int i=0; i<someClass.length; i++){
        some= someClass[i]; 
        this.value= some.value;
                    this.attributes = some.attribute;

        }
    }

            /**
             * Returns the Value.
             */
    public int getValue(){
        return value;
    }

            /**
             * Returns the Attribute.
             */
            public string getAttribute(){
        return attribute;
    }

Method in Function class is as follows:

public Testclass[] getTestClass(){

 //What to do?

}

Answer 1

Make attributes of the class TestClass be arrays. Create getters and setters if necessary. Create constructor initializer that accepts values or TestClass1 and initializes TestClass2 array. Create default constructor for TestClass2.

TestClass(TestClass1[] tc1, String attrName){

    tc = tc1;
    this.attrName = attrName; 
    if (tc != null) {
      tc2 = new TestClass2[tc.length];
      for(int i = 0; i< tc.length; i++) {
        TestClass2 t2c = new TestClass2(tc[i].getElements()); //this.tc.elements will   return an Array of SomeClass which is not implemented by me.
        tc2[i] = t2c;
      }
   }
}

/**
 * Returns the Testclass2 Array
 */
public TestClass2[] getTestClass2(){

  //What to do ?? 
  return tc2;
}

class TestClass2 {
   /**
    * Default constructor
    */ 
   TestClass2(){}
