Nope, both are different, however people usually think that these terms are similar. End stopped line occurs at the end of a line with the definite punctuation marks like in the lines from Keats’ Bright star,
“Bright Star, would I were as stedfast as thou art—
Not in lone splendor hung aloft the night.”
Caesura, on the contrary is a pause that mostly occurs in the middle, or beginning of a verse or sentence with or without punctuation marks, such as final two lines of Keats’ Ode on a Grecian Urn contains caesura,
Ye know on earth,|| and all ye need to know.”
Look at the pauses and punctuation marks in the middle of both these lines that I have shown with parallel symbols.
