What method should I use?
String sporocilo= JOptionPane.showInputDialog("Vpiši sporocilo");
int kodirano= sporocilo.length();
System.out.println(sporocilo);
System.out.println(kodirano);
for(int i=0; i<kodirano;i++){
if(sporocilo.length()%2!=0)
System.out.print(sporocilo.indexOf(i));

System.out.print(sporocilo.indexOf(i));

My Friend ask me this question and i am posting it here, if you have better approach please share
String getRandomMobileNumber() {
double random = Math.random();
Double randomten = random*1000000000.0;
return "0"+Math.round(randomten);
}
You can use this, see javadoc:
String phoneNumber = "0" + ThreadLocalRandom.current().nextInt(10000000, 99999999);

Can anyone help me to write code that find how many characters string has.
All you need is - int len = yourString.length();
StringUtils should provide you with something that you are looking for:
int count = StringUtils.countMatches("haahaahaa", "a");
System.out.println(count);

I am using Java and have some problems.
I made two BigInteger variables, p and q.
In my code, I want to add if function, like if(p=1 \ q=1).
I tried many ways but there was error. Do you know how to solve this?
Your question is not completely clear, but you need to use the BigInteger.equals() method, as in this example:
if (BigInteger.equals(p, BigInteger.ONE) || BigInteger.equals(q, BigInteger.ONE)) {
// do something
}
