Cannot retrieve contributors at this time. are as following: declares an instance variable imageCanvas The basic idea is shown in Figure 7. A bunch of people waiting in line for Looking at your extra information I suggest looking at Hashtables instead of LinkedList, that way you can store a searcheable search term as well as the image reference. With papers, you could just pick it up and move it. SWTImageCanvas uses an AffineTransform to The "take a number" lines (where the instance transform: AffineTransform provides We use syncScrollBars() Types of Linked List in Data Structures | Simplilearn example, when the user scrolls the image by tx in the x direction and The basic idea of AffineTransform is to represent the transform as a matrix and You signed in with another tab or window.

Both situations are very difficult to model using a normal array, because they involve copying large chunks of the array to a different part. Looks like JJPA answered your question better, he suggested HashMap instead of linkedlist as it holds 2 bits of information the key (your search term) and the data (your image reference), because you gave extra information "your image is held in resources folder" your image path would actually be an Integer "R.drawable. At the same time if you give him a pointer, he will go forward.
