Hi @khans5854,
See in this case you are using a custructor with no parameter and in that constructor you are calling another constructor with parameter … Here this(DEFAULT_CAPACITY) refers to the StackUsingArray(int capacity) constructor with int capacity as parameter … So in the case of constructor with no parameter you have to yourself assign a default value to be assigned to the fields like size and top and in this case DEFAULT_CAPACITY is the size of Stack… Hope you get this .
