Simple way is iterate and compare it. like below, I hope it may solve your problem int[] a = {1,2,2,3,4,3,5,5,7}; String b = “”; int count=0; for(int i = 0; i<a.length;i++){ for(int j=0; j<a.length;j++){ if(a[i]==a[j]){ count++; } } if(count>1){ count=0; b = String.valueOf(a[i]); }else{ count = 0; } } System.out.println(“last duplicate value : ” + … Read more

This is where methods might come in handy. First an outer loop because you’re counting down (from 4, in this example). static final int NR = 4; //for example static void main(String[] args) { int total = 0; for (int i = NR; i > 0; i–) total += calculateFactorial(i); //i += j; is the … Read more
Put your values in an array or List and randomise the index value…for example public int randomValue(int… values) { int index = (int)Math.round(Math.random() * values.length); return values[index]; } You could also use a List and use Collections.shuffle For example… public class Test { public static void main(String[] args) { int[] values = {4,100,2,20}; System.out.println(randomValue(values)); List<Integer> … Read more
Remove the continue; after line System.out.println(“The integer you entered ” + n + ” is not a PRIME NUMBER!”);. What continue; does is that it skips all the section of the loop that comes after it and performs the next iteration of the loop. 1 solved JAVA: Identify a prime number [closed]

The assumption here is that you want to print the number a character repeats before it changes. You can try: public class MyClass { public static void main(String args[]) { String input = “aaaaaggff”; char c = input.charAt(0); int count = 1; System.out.print(c); for (int i = 1; i < input.length(); i++) { if (input.charAt(i) … Read more

You could try this. String nbr = input.nextLine(); int a=nbr.charAt(0)-‘0’; int b=nbr.charAt(1)-‘0’; int c=nbr.charAt(2)-‘0’; Also, you could use substring and parse the result Using Integer.parseInt int a=Integer.parseInt(nbr.substring(0,1)); //Contains the leftmost digit 2 solved How do I select the first, second, or third digit from a String containing three digits?
