While Loops
package com.ack.learning;
public class WhileLoops {
public static void main( String[] args ) {
// simple loop that goes round and around until
// expression evaluations to false
double index = 99999;
while( index > 10 ) {
System.out.println( "index has value " + index );
index /= 2;
}
// this would be an infinite loop...
while( true ) {
break; // ...if we didn't break out here
}
// same as while loop, but with a subtle difference. code is alway
// executed before the loop iteration expression is evaluate
// do..whiles are the least used looping structures
do {
index *= 2;
System.out.println( "index has value " + index );
} while( index < 9999 );
}
}
