how get to main loop from nested loop after event of another thread












-1














while(true){//main loop
while(){}//inner loop
while(){}
}


This is main program in raspberry pi. I want to get main loop when program execute in nested loop after time expire. The time out function should be in another thread.



Best regards,
Thank you

If the question is to terminate a outerloop from the innerloop, you can do it using labelled loops in Java.



public static void main(String args) {


int count =0;

parentLoop:
while(true) { // Outer while loop is labelled as parentLoop
while(true) {
count++;
if(count==100) {
break;
}
}
while(true) {
count++;
if(count>150) {
break parentLoop; // Breaking the parentLoop from innerloop
}
}
}

System.out.println("Iterated "+count+" times. ");
}



  • Here Label name is parentLoop, a colon ( : ), followed by the while Loop

You can use labeled loops to break out of nested loops.



class Scratch {
public static void main( String args ) {
outermark: while(true){//main loop
while(true){
if(Math.random() > 0.6) break outermark; else break;

System.out.println("outer loop"); // unreachable code

Sample code that can achieve the same using java Thread class.



class Scratch {
public static void main( String args ) {


Thread thread = new Thread( () -> {
System.out.println( "thread running" );
while ( Math.random() < .6 ) {
System.out.println("thread is trying to break");
if ( Math.random() > .6 ) {
break;
}
System.out.println("thread failed to break");
}

System.out.println("thread completing");
} );

thread.run();
while ( true ) {
if ( !thread.isAlive() ) break;
}

System.out.println( "finished program" );
}
