I believe that what you want to do is this: public String[] getID(){ // Create an array of String of length staffNum String[] tempArray = new String[staffNum]; for(int x = 0; x < staffNum; x++){ // Affect the value Att[x] to each element of my array tempArray[x] = String.format(“Att[%d]”, x); } return tempArray; } 0 … Read more

The problem is in the display method: Node n = start.link; do { System.out.print(n.data+” -> “); n = n.link; } while(n.link != null); Imagine the point where n is the second to last node. We enter the loop, … Read more
Your count variable is named Q. You increment it on each loop in the increment statement Q = Z + y Where you have Z = text.length(); and y = user.length(); Now, since you don’t add those value to the previous Q value, you simply have Z + y so you only get the length … Read more
You error has nothing to do with the shown regex. The problem is because you use the matched result values as a parameter to replaceAll(), and those parameters are also regular expressions.
