What is the first difference?
Short answer. A constructor uses the class name; a method can use any valid name.
What does each one do?
A constructor sets up an object; a method performs a task.
Three differences
| Point | Constructor | Method |
|---|---|---|
| Name | class name | any name |
| Return type | none | yes or void |
| Runs | with new | when called |
Remember
| Constructor sets up |
| Method does a task |
Both have brackets. So what is different? Three differences. A constructor uses the class name. It has no return type. It runs with new, not by a call. A constructor sets up. A method does a task.
