In actual programming, sometimes it is necessary to break out of the loop when the conditional statement matches. In Java, it is controlled by break and continue statements.
"break" statement
The "break" statement is used to end the loop, that is All subsequent loops are no longer executed.
Example: Calculate the result of 1 2 3 4... 100. (Recommended learning: java course)
public class example1{ public static void main(String[] args){ int result=0; for(int i=1;i<=100;i++){ if(i>50) break; result+=i; } System.out.println(result); } }
Output result:
1275
Analysis: The program only calculated 1 2 3 4… ... As a result of 50, all subsequent loops are not executed, that is, when i=51, the loop ends.
In addition, the "break" statement can be used together with the switch statement, which will be explained in the next section.
"continue" statement
The "continue" statement is used to end the current loop and enter the next loop. That is, only this loop ends, not all loops end. , the subsequent loop still proceeds.
Example: Calculate the result of 1 2 3 4... 100.
public class example1{ public static void main(String[] args){ int result=0; for(int i=1;i<=100;i++){ if(i>50&&i<=60) continue; result+=i; } System.out.println(result); } }
Output result:
4495
Analysis: The program calculated the result of 1 2 3 …… 48 49 50 61 62 63 …… 100, but there was no Loop i=51,52...60.
