[ad_1] Your hasAnimals method needs to return a boolean value i.e. true or false based on the value of the type variable. You’re .. kind of on the right track, but you’re not honoring the requirements of the method. It shouldn’t print anything, and it shouldn’t return type because type is an int and not … Read more
[ad_1] You must initialize finished to false if you want to enter the while, and after, when job is done set finished to true to exit the loop boolean finished = false; while (!finished) { // ↑ ↑ ↑ ↑ ↑ →→→→→→ this means loop while finished == false randomNumber1 = random.nextInt(size); randomNumber2 = random.nextInt(size); … Read more
[ad_1] There is a method that fills an array of booleans with the selected value, this might be what you are after: Arrays.fill(boolean[] a, boolean val) Assigns the specified boolean value to each element of the specified array of booleans. [ad_2] solved java array of booleans all set to the same value [closed]
[ad_1] Your functions mypredicate and compare are merely thin wrappers over the binary operators == and <. Operators are like functions: they take a number of arguments of a given type, and return a result of a given type. For example, imagine a function bool operator==(int a, int b) with the following specification: if a … Read more
[ad_1] According to this: @Esailija Why no sense? If it is true return a true, if it is false return false, if it is ‘somestring’ also return false. Get it? – Registered User 31 secs ago You want function parseBoolean(value) { return typeof value == “boolean” ? value : false; } But this obviously won’t … Read more
[ad_1] I measured with the following code. public static void main(String[] args) { boolean myVariable = true; long startTime = 0; long endTime = 0; long duration1 = 0; long duration2 = 0; for(int i=0; i<1000; i++) { startTime = System.nanoTime(); myVariable = !myVariable; endTime = System.nanoTime(); duration1 += (endTime – startTime); startTime = System.nanoTime(); … Read more
[ad_1] You could try this: $res = true; foreach ($myarray as $item) $res &= $item; echo var_dump($res); A bit less elegant, but it should work. You’ll have an integer in the end because we’re using bit logic here, could be improved. For a OR case you could do almost the same thing: $res = true; … Read more
[ad_1] If the constructor runs , it itself means that an object has been instantiated. The constructor of a class is called it itself means that the object has been created. So, keep it simply.. public class Test { public float a1; public int b1; public double c1; public Boolean ifConsUsed = false; public Test(float … Read more
[ad_1] This can be used to loop over the array and print “yes ” or “no ” : boolean[] newbirds = {false, true, true}; StringBuilder sb = new StringBuilder(); for(boolean bird : newbirds){ sb.append(bird? “yes ” : “no “); } System.out.println(sb.toString()); [ad_2] solved java -change boolean to yes no
[ad_1] Your main issue was that you weren’t prompting them in the loop. import random x = random.randrange(1,1000) counter = 0 while True: guess = int(input(“I have a number between 1 and 1000. Can you guess my number?\nPlease type your first guess.”)) if guess == x: print (“Excellent! You guessed the number in”, counter,”tries.”) break … Read more
[ad_1] User Himal say use typeof.. so I can found the answer var myvar=5 alert(typeof myvar); //alerts “number” so to know kind of varible use typeof source : http://www.javascriptkit.com/javatutors/determinevar2.shtml [ad_2] solved How can I identify kind of variable I’m trying to compare in JavaScript?
[ad_1] There are versions of g++ (and versions of Visual C++ as well for that matter) for which on some platforms sizeof(bool) is not equal to 1. So no, you can’t assume that it will be the same on g++ and Visual C++. You can’t even assume that it’s the same on different versions of … Read more
[ad_1] I did it!!!! public static boolean sameDashes(String a, String b){ int minlength = Math.min(a.length(), b.length()); String smallstring=””; String bigstring=””; if(a.length()== minlength){ smallstring = a; bigstring = b; } else { smallstring = b; bigstring =a; } int counter = 0; int x=0; int y=0; do{ if(smallstring.equals(bigstring)){ return true; } else if(smallstring.indexOf(‘-‘,counter)!= -1){ y++; if(bigstring.charAt(smallstring.indexOf(‘-‘,counter))== … Read more
[ad_1] Your main method has to have the signature public static void main(String[] args) meaning you can’t mark it as returning a boolean. I don’t know what the point of this is but if you need it to return a boolean you should make another method to return a boolean. Your method needs to have … Read more
[ad_1] You’ll have to change the return type of your setter: public boolean setHeight(int newHeight) { if (1<=height && height<=10) { height = newHeight; return true; } else { return false; } } 4 [ad_2] solved Boolean in Mutator Method
