Answer:
sorry its late
Explanation:
/*
* Write a program that guesses every possible 4 digit passcode
* combinations until the correct passcode is guessed.
*
* The passcode is randomly generated and stored in the variable
* secretPasscode.
*
* Print out how many guesses it took to guess the correct passcode.
*/
function start() {
var correctCode = generateRandomPasscode();
var b = 0;
while(true){
var guessCode = generateRandomPasscode();
b++;
if(isCorrect(guessCode, correctCode)){
println("The correct passcode was " + guessCode);
println("It took you " + b + " tries to guess it");
break;
}
}
}
function isCorrect(guessCode, correctCode) {
return guessCode == correctCode;
}
function generateRandomPasscode() {
var randomPasscode = "";
for(var i = 0; i < 4; i++) {
var randomDigit = Randomizer.nextInt(0, 9);
randomPasscode += randomDigit;
}
return randomPasscode;
}

Answer:
public static String onlyDigits(String in){

}
A Complete program is wrtten in the explanation section
Explanation:
public class TestClass {
public static void main(String[] args) {
String a = "-jaskdh2367sd.27askjdfh23";
System.out.println(onlyDigits(a));
}
public static String onlyDigits(String in){
String digitsOnly = in.replaceAll("[^0-9]", "");
return digitsOnly;
}
}
The output: 23672723
The main logic here is using the Java replaceAll method which returns a string after replacing all the sequence of characters that match its argument, regex with an empty string
