In java, how does one jump out of the current multi-nested loop?

1. How to jump out of the current multi-nested loop in java? In java, if you want to jump out of multiple nested loops, you can define a label before the loop statement, and then use the break statement with the label in the code in the loop body to jump out of the outer loop. For example, [java] public static void main (String [] args) {OK: for (int I = 0; I <10; ++ I) {for (int j = 0; j <10; ++ j) {System. out. println ("I =" + I + "j =" + j); if (j = 5) break OK ;}} actually does not recommend this method, it is recommended that the results of the outer loop expression be controlled by the code of the loop body in the lower layer. For example: [java] www.2cto. compublic static void main (String [] args) {int arr [] [] ={{ 1, 2, 3 },{ 4, 5, 6, 7 },{ 9 }}; boolean found = false; for (int I = 0; I <arr. length &&! Found; I ++) {for (int j = 0; j <arr [I]. length; j ++) {System. out. println ("I =" + I + "j =" + j); if (arr [I] [j] = 5) {found = true; break ;}}}}
