create class method java code example
Example 1: classes in java
// this might help you understand how classes work
public class MathTest {
public static void main(String[] args) {
class MathAdd {
int num1;
int num2;
public int addNumbers() {
int addThemUp = num1 + num2;
return addThemUp;
}
}
MathAdd addition = new MathAdd(); // create a new instance of the class
// you can access variables from the class
addition.num1 = 10;
addition.num2 = 20;
// and use the method from the class to add them up
System.out.println(addition.addNumbers());
}
}
Example 2: how to make a class in java
// Public creates avaliability to all classes/files
public class Object {
// Instance of a variable per each class created
public int a = 1;
// Private restricts in local space (within these brackets)
private int b = 5;
// Defaults as public
int c = 0;
// Method Examples
void setB(int B)
{
b = B;
// No return b/c 'void'
}
int getA()
{
return b;
// Return b/c 'int' in front of method
}
}
