break in most of programming languages are interpreted or compiled as goto instructions, with the label to go to is compiler generated. A break statmenet within a for-loop, provides that there is no nested loops (while, do-while, repeat, etc) is to instruct the program execution to unconditionally goto (skip the condition check) to the next statement outside of the for-loop.
Conceptually or in abstraction, break should be considered as goto as well. Academically, there are conflicts: goto statements are bad but break-statement is acceptable. (they are the identical in certain context, should not be any discrimination or bias)
The following 3 segments will be compiled into similar instructions, and the same runtime efficiency and effectness:
Segment 1: normal construct
for (int i = 0; i < 2; i++) {//do something}
Segment 2: explicitly condition check with break-statement
for (int i = 0; ; i++) {
if (i >=2) break;
//do something
}
Segment 3: the equivalent of segment 2 with a gotostatement
for (int i = 0; ; i++) {
if (i >=2) goto OutOfLoop;
//do something
}
OutOfLoop:
Personal coding advise: choose break and gotostatements wisely. However, I have no need to use either statement in my professional coding career yet (switch or case statements may apply break-statements as well, yet, I could avoid switch statement, too)
A feature (break or goto) is provided by the language, does not mean that you have to use that feature in your code

How can you use the "break" statement in Java to prematurely exit a "for" loop?
In Java, you can use the "break" statement within a "for" loop to exit the loop prematurely. When the "break" statement is encountered, the loop will immediately stop executing and the program will continue with the code after the loop.
Can break statement be used without any loop?
The Break statement should generally get executed in some loop or switch statement. The below code will give compiler error. void main() { printf("12"); break; printf("14"); }
Compare break and continue statement?
Break - will force to terminate the loop you are in to the nearest outer block.Continue - will force to skip the rest of the code in loop and take next iteration.Break for example is not only limited to loop constructions, it is also used in switch statement in order to stop executing following cases (works as described above, jumps out of switch).
What will break do inside of a while?
The break statement inside a while loop will immediately terminate the loop's execution, regardless of the loop's condition. When break is encountered, control is transferred to the statement following the loop. This allows for exiting the loop based on a specific condition or event that occurs during its execution, rather than relying solely on the loop's condition to end.
Difference between break function and continue function?
The 'break' command will stop a loop from going any further, where a 'continue' command will start the loop over at the top (or bottom) of the loop, bypassing other instructions that may be in the loop. The 'continue' command will not stop a loop, but a 'break ' command will.Note: these statements aren't commands or functions.
What are break and continue statement in c language?
Break is used to exit the closest loop. Continue will cause the program to go to the beginning of the loop. for(int x=0;x<10;x++) { //continue; for(int y=0;y<10;y++) { break; } } The break statement causes the inner loop to stop at the first iteration. If the continue statement was uncommented, the inner loop would never be executed because the program would jump back to the beginning(until x = 10 of course).
How do you break a loop in a switch case statement?
using break; statement
Who can used to exit from a loop?
If you meant 'what can be used' then it is statement break.
What is loop breaking?
"break" is a key word in java,C++,... languages.Using this you can break loops. Eg:- for (int i=0;i<10;i++){ for(int j=0;j<8;j++){ System.out.println("this is a loop"); if(j==5){ System.out.println("Breaking inner loop"); break; } } } by using above codes you can break inner loop when you meet the condition j==5;
How do you exit in nested loop in java?
You may exit a nested loop in Java using a break with a label for the outer loop.
What is purpose of break statement?
to terminate a loop.
What is break in c?
The break statement is used to exit a loop or switch-case.
