我们来看一个实际示例,假设我们在处理用户输入,想要输入一个整数列表,并在用户输入负数时退出所有循环。 importjava.util.Scanner;publicclassBreakNestedLoops{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);outerLoop:while(true){System.out.println("请输入若干整数(输入负数退出):");for...
Java break statement is used to break a surrounding loop or switch statement, irrespective of the result of loop condition. If break statement is used in nested loops, only the immediate loop is broke. Break statement can be used inside a For loop, While loop, Do-while loop, and Switch s...
Nested Loops: In nested loops, a break statement will only terminate the innermost loop. Use labeled break statements if you need to exit multiple levels of nested loops. outerLoop: for (int i = 0; i < 5; i++) { for (int j = 0; j < 5; j++) { if (i == 2 && j == ...
// Java 示例 public class NestedLoopBreak { public static void main(String[] args) { outerLoop: // 标签(Java 不支持带标签的 break 在所有上下文中,这里仅作为说明) for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { if (i == 1 && j == 1) { break outerL...
Without the break statement, this loop would run forever. The break condition checks if count exceeds 3. $ node main.js 0 1 2 3 Break in nested loopsWhen used in nested loops, break only exits the innermost loop. main.js for (let i = 0; i < 3; i++) { for (let j = 0; j...
Nested Loop Break How can we break a loop directly from another nested loop? e.g: for(int i=0;;i++){ for(int j=0;;j++){ if(matrix[i][j]==100){ goto break_pt; //exit both loops } else if(j==10){ break; } } } break_pt: ...

break Keyword in Java with Examples The break keyword is used to prematurely exit a for, while, or do while loop or to mark the end of a case block in a switch statement. Let’s discuss how to use break keyword in for loop, while loop and switch statement with examples. ...
Using break inside a nested loop Using break with labels. When using nested loops, we can terminate the outer loop with alabeled break statement. Working of labeled break statement in JavaScript As you can see in the image above, theouterlooplabel identifies the outer loop. ...
