Anyone Help me to explain how does this code works
DataInputStream in= new DataInputStream(new FileInputStream(steg.getFile()));
in.read(byteArray, 0, fileSize);
Cipher cipher= Cipher.getInstance("DES");
cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(password.substring(0, 8).getBytes(), "DES"));
it's a forum another person had answered for this question. so if u know programming u can explain ,,,, how does this code process... it's Audio steganography using LSB technique by this u wouls have answered.
HI im tryin to implement dijkstra's algorithm in java but my output is not correct. The output should be [0,492,665,114,452,999] but i keep getting a different range.Can anybody help please as i need this for my assignment. Thnks
public ArrayList <Integer> dijkstra (int start, int end) // start = 0 & end = 999
int N = adj.length;
HashMap <Integer,Double> Q = new HashMap <Integer,Double>(); // key,value
ArrayList <Integer>  paths = new ArrayList [N]; // paths 1000//System.out.println( "paths.Length" + paths.length); for (int i=0;i<N;i++) // end = 999
Q.put(i,Double.POSITIVE_INFINITY); // blank i = 0 to 999(keys/vertex)//System.out.println("Q @ " +Q.get(999));
paths[i]=new ArrayList <Integer>();
paths[i] = new ArrayList<Integer>(start); // blank distances
HashSet <Integer> S= new HashSet(); // contains unique elements
S.add(start); // blank
Q.put(start,Q.get(start)); //blank while (!Q.isEmpty())
int v = findSmallest(Q); // blank//System.out.println("key of Q " + v)if (v==end && Q.get(v)!= Double.POSITIVE_INFINITY) // blank Q ! map to vreturn paths[end]; // blankdouble w = Q.get(v); // blank
S.add(v); // blankfor(int u: neighbours(v))
double w1= adj[u][v] + w; // adj contains all the weigths of the graphif (w1 < Q.get(u))
returnnew ArrayList <Integer> ();
You prevent yourself from getting help because we don't have the input data and we don't have actual result.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute, it is an incredible learning tool.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
