You can’t declare a try-catch in class level scope, just put it inside a method. Here is an example with a possible constructor that initializes your members: public SlickTTF(){ try{ awtFont = Font.createFont(Font.TRUETYPE_FONT, fontFile); awtFont = awtFont.deriveFont(20f); font = new TrueTypeFont(awtFont, true); }catch(Exception e){} } Now you can create an SlickTTF object as SlickTTF example … Read more
I’m unsure whether I’m helping you or giving you a load of new problems and unanswered questions. The following will store the count of times the class Founder has been constructed in a file called useCount.txt in the program’s working directory (probably the root binary directory, where your .class files are stored). Next time you … Read more
In a nutshell the difference is simple: the default implementation of equals() and hashCode() for java.lang.Object will never consider two objects as equal unless they are the same object (i.e. it’s “object identity”, i.e. x == y). the default implementation of equals() and hashCode() for records will consider all components (or fields) and compare them … Read more
You could keep track of what your first number is, and check if it is zero, then do nothing. if(newValue == true) disp.setText(“0”); else { if (!firstNumber.equals(“0”) disp.setText(disp.getText().toString() + “0”); newValue = false; } solved I am trying to build a simple calculator [closed]
You can use BoxLayout and set its second parameter as BoxLayout.Y_AXIS to use FlowLayout in “vertical mode” Like this: panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); Does that answer your question? 2 solved layout with one columns, and increasing row number in java [closed]
This is due to the format you used as “yyyy-MM-DD”. The parser will parse in the sequence way: Your input value is “2018-03-08” yyyy – will bring to the year 2018 MM – will bring to the month MARCH But what is DD? It’s the number of the days from the beginning of the year. … Read more
Use If Statement as follow if(bWeek == Week && bMonth == Month) { getBonus = true; } == is used to compare = is use to assign value solved If statement comparing 2 conditions of ints runs as boolean
I have one StringBuilder, a non immutable object and if I use a method on the object it will return me a new value of the object with the same reference object. Not always will a method return you the same reference object. It might create a new object and return that. Its always better … Read more
It is suggested to use HttpUrlConnection instead, since HttpClient is deprecated. For further research; http://developer.android.com/reference/java/net/HttpURLConnection.html solved issue with api code android studio
As per my comments, get user interaction out of the search method, in other words, avoid using System.in and System.out (except for temporary use for debuggin). Instead, pass in a String cnic parameter, so that other code that has user interaction can query information from the user, get the desired cnic String and pass it … Read more
I have read your comment and I think you just need to place ID, name, lastName variables outside of your main function and make them static. You can also do this with the key array. This way other methods can work with these variables. import java.util.Random; public class YEAH { private static final Random randomChar=new … Read more
X509EncodedKeySpec is the SubjectPublicKey part of a certificate. So you probably need to decode this structure. You could look at BouncyCastle for C# and check out Org.BouncyCastle.Asn1.X509.SubjectPublicKeyInfo.GetInstance(byte[]) 1 solved convert java code with RSA to c#
Here is one solution with a reverseOrder method in a Collections class in java import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import java.util.List; public class test { public static void main(String[] args) { List<List<Integer>> numlist = new ArrayList<List<Integer>>(); List<Integer> somelist = new ArrayList<Integer>(); somelist.add(5); somelist.add(6); Integer[] aa = new Integer[somelist.size()]; Arrays.sort(somelist.toArray(aa), Collections.reverseOrder()); somelist.clear(); for(int i =0;i<aa.length;i++) … Read more
Your question really leaves a fair amount up in the air as to what is really required but as I understand it through reading the comments… You have 4 Items within your List (A, B, C, and D). You want to create a List pertaining to each particular Item. If there are 10 data elements … Read more
You are making your code way too complicated, use a HashSet<String>, which will guarantee uniqueness and will return whether the element was already in the set. public class DuplicateEle { public static void main(String args[]) { Set<String> seen = new HashSet<>(); String[] arr = { “hello”, “hi”, “hello”, “howru” }; for (String word : arr) … Read more
