I’ve created a basic class for you that will save the wins to a text file and retrieve them from a text file. import java.io.File; import java.io.FileNotFoundException; import java.io.PrintWriter; import java.util.Scanner; public class WinsFileManager { String path = System.getProperty(“user.home”).replace(“\\”, “\\\\”) + “\\”; public int getWins(String fileName) { String fullPath = path + fileName; int wins … Read more
After you set your variable “original” to the next line of text, you can call the replaceAll() string method to strip away any unwanted characters with a specifier parameter. Also, you can call toLowerCase() to get all lower case strings. String original, reverse = “”; Scanner in = new Scanner(System.in); System.out.println(“Enter a string to check … Read more
send data from inputAddrss, Intent intent = new Intent(getBaseContext(), SignoutActivity.class); intent.putExtra(“url”, YOUR_EDIT_TEXT.getText().toString()); startActivity(intent); receive data in MainActivity, String s = getIntent().getStringExtra(“url”); then load into webview view.loadUrl(s); solved webview load url from input text in another class [duplicate]
This is due to the fact that Eclipse automatically defaults to JRE 6. In order for you not to get those nasty warning triangles, you will need to use the JRE 8. The following is how you might resolve it: Preliminary fix Right click one of your prjects > Build path > Configure build path … Read more
Break will leave the loop, so booth solutions will only ‘iterate’ over the first item. The second solution without break would be right. (Both solutions would work if you use continue instead of break) solved If Else Best Approach In Java [closed]
The problem you are experiencing is with this piece of code: int percent = (totalDataRead * 100) / filesize; Download.status.setText(totalDataRead / 1024 + “kb/” + filesize / 1024 + “kb”); setProgress(percent); Your value for percent must be outside the range 0…100 as the exception message is coming from the setProgress method: http://docs.oracle.com/javase/7/docs/api/javax/swing/SwingWorker.html#setProgress(int) Note: IllegalArgumentException – … Read more
The message says: NetworkOnMainThreadException. In Android applications, one may not execute network code on the Main thread. This means you have to create a separate thread for your code. This can by done via an implementation of the AsyncTaskclass. Look at the documentation solved HTTP POST call from Android [duplicate]
You just need to keep both the maximum price and the name of the product with that maximum price. For example, Product[] products = // your products. Product mostExpensiveProduct = product[0]; for (Product product : products) { if (product.getPrice() > mostExpensiveProduct.getPrice()) { mostExpensiveProduct = product; } } System.out.println(“Most expensive product is ” + mostExpensiveProduct.getName() + … Read more
This enum is optional, but helps with code clarity: enum Field { INT_HX, INT_EX, INT_RX, INT_MX, INT_IX } Then test the values: Field largestField = Field.INT_HX; int largestValue = intHx; if(intEx > largestValue) { largestField = Field.INT_EX; largestValue = intEx; } if(intRx > largestValue) { largestField = Field.INT_RX; largestValue = intRx; } if(intMx > largestValue) … Read more
place this line after setcontent view text=(TextView)findViewById(R.id.text); like : @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.image); text=(TextView)findViewById(R.id.text); this.detector=new GestureDetectorCompat(this,this); } solved onScroll method not working [closed]
You are using the * to separate “main items” but it can also be inside the main item. Your requirements look odd, but lets assume for the sake of argument that you are getting your input data like this and you want to split it like you suggested. That means that every * that is … Read more
You need to declare a variable to hold the sum: int f, sum = 0; for (int k = 1; k <= 6 ; k++){ System.out.println(“Type ” + k +”. number”); f = userInput.nextInt(); sum += f; } solved Counting amount in Java loop [closed]
Yes, by design. The single-equals means set the left operand to the right operand. The 4th element of Array1 is set to the value of the fourth element of Array2. This changes the contents of the array, though not the structure. If you’re trying to do a comparison, you’ll want to use == for “is … Read more
You certainly can send mail from within Java SE, you just need to include two jar files with your project: mail.jar and activation.jar. Java EE contains a number of technologies that can be used outside of a Java EE container. You just need to add the relevant library files to your project and thus your … Read more
I don’t really have time to study the problem now, but here’s a bit of a simplification: // Y2 = Y + (Y = 0) int Y2 = Y; Y = 0; // J2 = J + (J = 0) int J2 = J; J = 0; // Note that, since we’ve just set Y … Read more
