Java Break out of for loop
In loop programming the program flow is continued till
the specified loop condition generates Boolean value true. Here in the example a
brief introduction about Java break label is demonstrated, along with this
concise intro, how to come out of for or any loop is also taught.
In Java loops are required basically for repeating tasks and for controlling the
behavior of loops, loops conditions and Java labels are passed inside the
loop statements. These Java labels are break and continue respectively. 'break'
is mainly used in stopping the program
control flowing inside the loop and bringing it out of the loop. While
'continue' label just stops the program flow at line where this label is
passed and returning the control at the beginning of the loop for re-starting
the loop process.
In the example below, functioning of labeled break statement is demonstrated.
import javax.swing.JOptionPane;
public class Java_Break_out_of_for_loop {
public static void main(String args[]){
int i = 0;
String strb = "break", strc = "continue", choice = "";
JOptionPane.showMessageDialog(null, "Tip of the day.. \n\tAllow the label 'break' to close 'for' loop", "Welcome to roseindia message zone", 1);
roseindia:
for (;; i++) {
choice = JOptionPane.showInputDialog(null, "Type break to terminate the loop\n or Type continue to carry on inside the loop", "Input option box", 2);
if(choice.equals(strb)){
JOptionPane.showMessageDialog(null, "You are now out of ' for ' loop\n under label
roseindia", "Break Label ", 1);
break roseindia;
}
else if(choice.equals(strc) ){
JOptionPane.showMessageDialog(null, "You are now at the beginning of the loop\n You have continued the loop", "Continue Label", 1);
continue roseindia;
}
else {
JOptionPane.showMessageDialog(null, "Press enter to continue", "Label does not match ", 0);
continue roseindia;
}
}
}
}
