I've been using getters and setters in this java code .. so in my Class A I get the user input and I tried this and it runs perfect and I tried to output the user input and the answer is same so I've go to the Class B in class B I need to search .. the user will search and output the answer if true .. in class A

example the user input Student id : 12 and he searched it in class B it must output ..

but my problem I don't know how I can link the array from the Class A to Class B so I can manage to search is ..

  • What do you mean by "link the array". Can you post some code for A and B showing us what you are trying to do? –  Aug 04 '15 at 05:41

  • System.out.print("ENTER NAME: "); mskt[rec.a].setName(br.readLine()); System.out.print("ENTER ID: "); mskt[rec.a].setId(Integer.parseInt(br.readLine())); System.out.print("ENTER MATH GRADE: "); //i ask the user to input and store the value at int a .. int a is declared as global .. i want to search =its values in class B – Joshua Gonzales Aug 04 '15 at 05:42

  • I suggest you add all the relevant code to your post. You will get better help faster if it's possible to "see" what you're doing. – ChiefTwoPencils Aug 04 '15 at 05:55

You can pass an array to a method call, like this:

// void someMethod(String[] someStringArray);
String[] theArray = new String[]{"foo", "bar"};
someMethod(theArray);

or to some constructor:

// SomeClass(String[] someStringArray);
String[] theArray = new String[]{"foo", "bar"};
SomeClass foobar = new SomeClass(theArray);

  • in class A i declared this :rec[] mskt=new rec[10]; mskt[rec.a]=new rec(); /rec is the class name , mskt is object name .. im not sure how can i access this in class B ? – Joshua Gonzales Aug 04 '15 at 05:50
