printing

问题 Hi there I've had a search output formats and formats had no luck. I couldn't find right documentation for it and I really want to learn how this code works if somebody could enlighten me please? print ("Survived: %i (%.1f%%)"%(len(survived), float(len(survived))/len(train)*100.0)) print ("Not Survived: %i (%.1f%%)"%(len(not_survived), float(len(not_survived))/len(train)*100.0)) print ("Total: %i"%len(train)) My questions is inside the code % symbols %i %.1f%% (I believe one decimal) I just

问题 Basically I want my code to enable the user to enter x amount of integers (they chose x), then they will then store each of their inputted integer values in my array. For some reason when I print my array out after all values have been entered: I get this: Code: Scanner input = new Scanner(System.in); System.out.print("How many integers will you enter:"); int amount = input.nextInt(); int myArray[] = new int[amount]; for (int counter = 0; counter < amount; counter ++){ myArray[counter] =

问题 I have problem I would like to compare two files. First files is reference: ABCA4 INHR AMT INHR BTK ONKO1 PAP ONKO2 Second file is for compare: 3 1:2 T ENG1 ABCA4 ff 3 1:2 T ENG1 ABCA4 gg 5 1:4 A ENG20 AMT ll 6 1:5 G ENG12 BRB ds 7 1:6 T ENG8 PAP rg 7 1:6 T ENG8 PAP tt And I want compare $1 from first file with $5 from second file and if there is match print between $5 and $6 in second file the $2 from first file: 3 1:2 T ENG1 ABCA4 INHR ff 3 1:2 T ENG1 ABCA4 INHR gg 5 1:4 A ENG20 AMT INHR ll

问题 So I have this piece of code, very basic stuff that I'm working on. I stumbled upon this "slow type" thing, that I like but if I use it instead of all print functions, most of my output is written on one row. import sys, time def print_slow(str): for letter in str: sys.stdout.write(letter) sys.stdout.flush() time.sleep(0.02) print_slow('What\'s your name?') name = raw_input() print_slow('My name is ' + name) if name == 'alex' or name == 'Alex': print_slow('That\'s a good name') if name ==

问题 So i keep on getting an error on the next code. And I have no idea what i'm doing wrong. The error is The method printArray(T[]) in the type main is not applicable for the arguments (int[]) public class main { public static void main(String[] args) { Oefening1 oef = new Oefening1(); int[] integerArray = {1,2,3,4,5}; printArray(integerArray); } public static <T> void printArray(T[] arr){ for(T t: arr){ System.out.print(t + " "); } System.out.println(""); } } 回答1: When it comes to generics,

问题 I'm trying to print an array of seven strings, and am using a get method to return them to the min before printing, but whenever I run it some random gibberish shows up on the console: [Ljava.lang.String;@6d6de4e1 Here is my get method String[] getStuff(){ return stuff; } And here is the print method from the main class: System.out.println(trex.getStuff()); The array is completely valid and full of Strings, so I'm not sure what this error is. 回答1: You want to print the string values of the

问题 Chrome 77 has stopped respecting the print() embedded JS in PDFs to initiate/open the print dialog after a PDF has been loaded. For example, open the below file in Firefox, Chrome 76, or in Acrobat and you'll see the print dialog appear. In Chrome 77 it is no longer appearing. Specifically, in my case and on three other computers I tested this on, version 77.0.3865.75. https://cdn.dealrcloud.com/assets/test/Invoice-1003.pdf Is this a new setting we can adjust/modify or is this a permanent

问题 Here is my code for string concatenation. StringSecret.java public class StringSecret { public static void main(String[] args) { String s = new String("abc"); s.concat("def"); System.out.println(s); } } I expected that the output will be "abcdef" but I am getting only "abc" printed. What's the problem !. 回答1: In java, string objects are immutable . Immutable simply means unmodifiable or unchangeable. Once string object is created its data or state can't be changed but a new string object is
