Answer 3

https://docs.oracle.com/javase/9/docs/api/java/lang/String.html#indexOf-java.lang.String-

All of the overloaded versions of indexOf return an int, the index of the first occurrence. If you put an int as a separate parameter this tells the start index to search from, so this could be used when you want to find subsequent occurrences. If you meant letters and numbers in the string argument then you get the index where that substring first occurs, otherwise -1 if you don't find it

Answer 4

eg
String x = "Abcd123";
System.out.println(x.indexOf('b'));
System.out.println (x.indexOf('3'));

output:
1
