Which line reverses the string?
Short answer. r = ch + r, joining each character in front.
Which method compares the text of two strings?
equals().
Remember
| r = ch + r reverses |
| Compare with equals() |
MADAM reads the same both ways. How does Java check? Put each character in front of r. That reverses the word. Then equals compares them. Here p is true. Join in front to reverse. Compare strings with equals, never double equals.
