Consider the below function:
void strop(String s) {
char a = s.charAt(3);
int b = s.indexOf('M');
String t = s.substring(3,6);
boolean p = s.equals(t);
System.out.println(a + " " + b + " " + t + " " + p);
}
What will be the output for strop("COMPUTER")?
Answer
P 2 PUT false
Working
s.charAt(3)returns the letter at index 3 ofswhich is P. This gets assigned to variablea.- Index of letter M in
sis 2. s.substring(3,6)returns a substring ofsstarting at index 3 till index 5. So PUT gets assigned tot.- As PUT is not equal to the value of
s(which is COMPUTER) sopbecomes false.
