java - I have 2 classes in Bluej and want to make a field in one of the classes be of type of the other class. How would I do this? -

-

i have made 2 classes in project in bluej , have link them making new field in main class of type of second class.

what syntax this?

i may interpreting question wrong but, assuming classes class1 , class2, can have class1 take in instance of class2 so:

public class class1{        class2 otherclass;        public class1(class2 otherclass){           this.otherclass = otherclass;       }  }

now class1 has instance of class2 can play with.

you may have class1 create class2 object instead of passing 1 so:

public class class1{        class2 otherclass;        public class1(){            otherclass = new class2();       }  }
