identify the correct usage of the advanced for loop? Assume that'myarray' is an array having some 'double' type values.
1) for(double value=:myArray){
System.out.println(value);
}
2). for(double value=0;myArray.length()-1){
System.out.println(value);
}
3). for(double value =0:myArray){
System.out.println(value);
}
4). for(double value:myArray){
System.out.println(value);
}
