I got a problem with a question.
Question: an Array instance variable called people has been set up by the line:
public Person[] people;
Write the line that will initialise/instantiate it to take 100 objects of type Person.
My answer:
public Person[] people;
double []people = new Person [100];`
The error that I am getting is this:
Main.java:8: illegal start of expression
public Person[] people;
What can I do to solve this problem?
public is keyword for definition method or attribute visibility in a class. If you are using only variable then it is without this keyword. So it should be Person[] people;.
Also I think you have a mistake in double []people = new Person [100]; It should be people = new Person [100]; but this is not initialization of 100 objects but only 1 array of 100 references to 100 NULLs. You have to use a for cycle to call 100x people[i] = new People();
This should be outside of your main method, within the class:
public Person[] people;
You can then initialize it without redeclaration:
people = new Person[100];
Since this is written in main, the public is unecessary, so your code can be simplified to:
Person[] people;
people = new Person[100];
