Comparisons are similar to the ordering that one might find in a dictionary. The return of this method is an int which can be interpreted as follows: returns < 0 then the String calling the method is lexicographically first (comes first in a dictionary) returns == 0 then the two strings are lexicographically equivalent returns … Read more
Trying to enumerate all the different possible strings in the array is generally a bad idea and not the correct way to write your program. Sure your example works, but what would happen if your set of possible strings was not just {‘this’, ‘is’, ‘a’, ‘test’}, but instead had say 10000 elements? What if you … Read more
string str = “\x45 \xac \x1b \5c” http://msdn.microsoft.com/en-us/library/aa691090%28v=vs.71%29.aspx 4 solved Can we type strings with use of hex codes in c# like we type integers like that int a = 0x0000cd54;?
Interning is making identical immutable objects hold the same reference to save memory. When s3 is interned, it is set to point to s1 from the inter pool(as it is a literal it is added there readily). Since they have the same reference, == returns true. 1 solved How System.out.println(s1==s3.intern()); //return true? [closed]
I want to print a string array containing numbers organized in columns. The array contains {“2″,”1″,”3″,”16″,”8″,”3″,”4″,”1″,”2”} I want to print them in this form 2 16 4 1 8 1 3 3 2 For the the given code of yours, you can do following changes to achieve the result. Find the array length using sizeof(arr)/sizeof(*arr);. … Read more
You could split over a specific string (degree character for example), store in a String array and parse the first element. Something like this: String str = “47°C” String[] strArray = str.split(“°”); int number = Integer.parseInt(strArray[0]); solved I have a string with a number and a letter, is there a way to move the integer … Read more
GPA = Double.parseDouble(df.format (((double)qualityPoints) /(double)(sumOfHours))); int qualityPoints = 0; int sumOfHours = 0; double GPA = 0; DecimalFormat df = new DecimalFormat(“0.00”); GPA = Double.parseDouble(df.format (((double)qualityPoints) /(double)(sumOfHours))); No compilation error for this. 8 solved Converting String to Double in Java [closed]
First, use split() to split the input into a list. Then, you need to test isnumeric() on every element of the list, not the whole string. Call int() to convert the list elements to integers. Finally, add the sum to counter, not counter_item. my_list = input(“Input your list.(Numbers)\n”).split() while not all(item.isnumeric() for item in my_list): … Read more
A = [s for s in A if s.strip() != ”] or A = [s for s in A if len(s.strip()) > 0] 1 solved How to remove str. Of spaces from list [closed]
If you want to check if a string i contains string j, you can do it using i in j. Then comes the part how do you want the output actually. What my approach was to go through the list1 and for each of them go though the list2 and check if element of list2 … Read more
Map over the array and assign each key value pair to a new object after converting it to a string. const array = [{abcd:1, cdef:7},{abcd:2, cdef:8}, {abcd:3, cdef:9}]; array.map(el => { const stringObj = {} Object.keys(el).forEach(key => { stringObj[key] = el[key].toString(); }) return stringObj; }) 1 solved transforming elements in array from numbers to string
Here’s the first one that I see: input(“\n\n\nPress enter to exit menu) And the second one is that you forgot to escape the newline in code at the end of this line: + \n by the patient himself/herself. 3 solved EOL while scanning string literal, file won’t run [closed]
Since I didn’t get my desired answer rather got multiple downvotes, I am accepting this one… (\$\{\w+\.\w+\}) Thank you all for your answers. solved Regular Expression To Find a Substring from a text with a particular matches, the sequence may come multiple times in the text
In C, strings are stored as null-terminated arrays of characters. This means that there are many ways to represent the same string: everything in the array of characters after the first null byte is ignored, as far as the value of the string is concerned. When the first gets call reads HelloWorld, it stores the … Read more
I think you are misunderstanding the “:” notation for the lists. upper[:3] gives the first 3 characters from upper whereas upper[3:] gives you the whole list but the 3 first characters. In the end you end up with : upperNew = upper[:3] + upper[3:] = ‘ABC’ + ‘DEFGHIJKLMNOPQRSTUVWXYZ’ When you sum them into upperNew, you … Read more
