Call a Class From another class [closed]

Suposse you have

Class1

public class Class1 {    //Your class code above}

Class2

public class Class2 {}

and then you can use Class2 in different ways.

Class Field

public class Class1{    private Class2 class2 = new Class2();}

Method field

public class Class1 {    public void loginAs(String username, String password)    {         Class2 class2 = new Class2();         class2.invokeSomeMethod();         //your actual code    }}

Static methods from Class2Imagine this is your class2.

public class Class2 {     public static void doSomething(){     }}

from class1 you can use doSomething from Class2 whenever you want

public class Class1 {    public void loginAs(String username, String password)    {         Class2.doSomething();         //your actual code    }}

If your class2 looks like this having static members

public class2{    static int var = 1;    public static void myMethod()    {      // some code    }}

Then you can simply call them like

class2.myMethod();class2.var = 1;

If you want to access non-static members then you would have to instantiate an object.

class2 object = new class2();object.myMethod();  // non static methodobject.var = 1;     // non static variable

Simply create an instance of Class2 and call the desired method.
