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(); } }
