一个简单的for循环

直接上代码，复习基础，谢谢！

public class For {
public static void main(String[] args) {

for (int i = 0; i <10; i++) {
System.out.println("a="+i);
}

//加强版for循环
int [] numbers = {10, 20, 30, 40, 50};

for(int x : numbers ){
System.out.print( x );
System.out.print(",");
}
System.out.print("\n");
String [] names ={"James", "Larry", "Tom", "Lacy"};
for( String name : names ) {
System.out.print( name );
System.out.print(",");
}
}
}
