Top-level classes cannot be static, because the static keyword represents a relation between a class/member/method and the enclosing class. As the top-level classes don’t have an enclosing class, then the static keyword doesn’t makes sense in this case. solved Applying static keyword to a class in java [duplicate]
The problem with your code is this check: if (ch == ‘O’) { if (!((inp.charAt(i + 1)) == ‘X’ || (inp.charAt(i – 1)) == ‘X’)) { count++ } } Here you check for only a case where there is O not surrounded by X. But this check doesn’t work for cases like *OOXOO*. You’ll get … Read more
In general you can create strings with placeholders using: String result = String.format(“%s,%s”, v1, v2); If you are using JDBC, you can use a PreparedStatement, for example: PreparedStatement statement = connection.prepareStatement(“UPDATE table1 SET column1 = ? WHERE column2 = ?”); int i = 1; statement.setInt(i++, v1); statement.setInt(i++, v2); statement.executeUpdate(); For creating JDBC queries the PreparedStatement … Read more

A java.io.File object does not represent a file. What it actually represents is a file system pathname; i.e. a name for an object in the file system that may or may not exist. So your program is not “receiving” a file at all, and the only things that you could do with the object that … Read more
When you call a function recursively, they add the new function to a stack until have a final result (return). When it occurs, you go back return by return in the stack. An Execution example: First Round wacky(4, 6): 4 <= 1? No, so call wacky(4 – 1, 6 – 1) Second Round wacky(3, 5): … Read more
Hi!This is your code without errors! So, I changed somethings, I’ll list them to get clearer. To use “Name” and “Id” in more than one method, it is easier if they are global variables. When calling the “test” method you need to pass the values, so in the “entry” method the values are passed. The … Read more
The modulo operator, more or less, just gives you the remainder of the division. So: 12 % 4 = 0 since 12 / 4 = 3 remainder 0 Whereas, since 12 doesn’t divide 4: 4 % 12 = 4 since 4 / 12 = 0 remainder 4 For more information, see the Wikipedia article, or … Read more
The service has been shut down since April 2011. You can use Yahoo! Search BOSS instead, but you’ve to pay for it. You may consider switching to Google Custom Search which is free up to 100 queries per day, afaik. solved Searching in yahoo using java [closed]
change for (int i = 0; i <= resultArray.size(); i++) { into: for (int i = 0; i < resultArray.size(); i++) { you can use for(String s: resultArray){…} as well, if you don’t care about the index so much… 1 solved ArrayIndexOutOfBounds in android [duplicate]

I think it’s a very bad idea to calculate two very large numbers and hope that the quotient comes out as something sensible. Start by taking the natural log: ln(n!/(q!)^r) = ln(n!) – r*ln(q!) You can use gammaln() for the two function values, simplify, then take exp() to get the result you want: value = … Read more
LocalDate and ThreeTenABP String dateString = “2019-11-27”; LocalDate date = LocalDate.parse(dateString); int epochDay = (int) date.toEpochDay(); System.out.println(epochDay); This snippet outputs: 18227 The documentation explains: The Epoch Day count is a simple incrementing count of days where day 0 is 1970-01-01 (ISO). So my suggestion is that this number is fine for feeding into your BarEntry … Read more
Java is not C++. You need to write swap differently in Java. public static void swap(int[] a, int i, int j) { int t = a[i]; a[i] = a[j]; a[j] = t; } Java doesn’t support & and * unary operators. On the plus side you don’t need to pass the length of an array … Read more
