how to access non static method in static method code example

Example 1: can non static method access static variable

Yes, a non-static method can access a static
variable or call a static method in Java.
There is no problem with that because of
static members . both static variable and
static methods belongs to a class and can be
called from anywhere, depending upon
their visibility. For example, if a
static variable is private then it can
only be accessed from the class itself,
but you can access a public static variable 
from anywhere by calling with classname.

Example 2: static vs non static java

// Static vs Object Called
// Static Methods don't require you to call a constructor

// Initialize statically
public class MyClass {

  private static int myInt;

  static {
      myInt = 1;
  }

  public static int getInt() {
      return myInt;
  }
}

// Then call it
System.out.println(MyClass.getInt());

// VS Constructor

public class MyClass {
 
  private int myInt;
  
  public MyClass() {
    myInt = 1;
  }
  
  public int getInt() {
	return this.myInt;
  }
}
// Then call it
MyClass myObj = new MyClass();
System.out.println(myObj.getInt());
