Say I have this view with two subviews A and B, A and B has a color property mColor,

I want a function in the parent view that has this signature: int getColor(int x, int y), which for any given x and y coordinate, return the color at that position, if the x and y coordinates land and the two shapes are overlapped, return the average color of A and B

The problem I am running into is i see myself doing a lot of conditional checks, checking if A is left of B or if A is right of B etc. I feel like I am missing some key intuition

I have a Point class that handles the coordinates”

public class Point {     private final int mX;     private final int mY;      public Point(int mX, int mY) {         this.mX = mX;         this.mY = mY;     }      public int getX() {         return mX;     }      public int getY() {         return mY;     } } 

Here is my subview class:

public class Chart  {      private int mColor;     private Point mTopLeft;     private Point mBottomRight;      public Point getTopLeft() {         return mTopLeft;     }      public Point getBottomRight() {         return mBottomRight;     }      public Chart(int mColor, Point topLeft, Point bottomRight) {         this.mColor = mColor;         this.mTopLeft = topLeft;         this.mBottomRight = bottomRight;     }      public int getColor() {         return mColor;     }      public Point getTopRightCorner() {         return new Point(getBottomRight().getX(), getTopLeft().getY());     }      public Point getBottomLeftCorner() {         return new Point(getTopLeft().getX(), getBottomRight().getY());     } } 

My parent view class:

public class View {      private Chart mChartA;     private Chart mChartB;      public View(Chart chartA,                 Chart chartB) {         mChartA = chartA;         mChartB = chartB;     }      public boolean doChartsOverlap() {         boolean isOverlapped = true;          if(isChartALeftOfChartBInX() || isChartARightOfChartBInX()) {             isOverlapped = false;         }          if(isChartABottomOfChartBInY() || isChartATopOfChartBInY()) {             isOverlapped = false;         }         return isOverlapped;     }      public final boolean isChartALeftOfChartBInX() {         return mChartA.getBottomRight().getX() <= mChartB.getTopLeft().getX();     }      public final boolean isChartARightOfChartBInX() {         return mChartA.getTopLeft().getX() >= mChartB.getBottomRight().getX();     }      public final boolean isChartATopOfChartBInY() {         return mChartA.getBottomRight().getY() <= mChartB.getTopLeft().getY();     }      public final boolean isChartABottomOfChartBInY() {         return mChartA.getTopLeft().getY() >= mChartB.getBottomRight().getY();     }      public void setChartA(Chart mChartA) {         this.mChartA = mChartA;     }      public void setChartB(Chart mChartB) {         this.mChartB = mChartB;     } }
