Exits the current loop and exits the loop __java base

Scene:

When you import more than one piece of data through Excel (insert multiple data at once into the database), to read, parse Excel, and loop into each piece of data, before inserting a piece of data to determine whether the data already exists, if there is a continue exit the current loop, into the next cycle. For example:

Break : Jump out of the loop

for (int i = 0;i < 10;i++) {

if (i = = 2) {

Break

}

System.out.println (i);

}

continue: End this cycle

for (int i = 0;i < 10;i++) {

if (i = = 2) {

Break

}

System.out.println (i);

}

Output: 0,1,3,4,5,6,7,8,9 (not output 2) because when i==2, the execution of System.out.println (i) is skipped, directly to the next loop.
