JAVA一些（IDEA编译器）简写法

public class j1 {
    //prsf
    private static final int a=1;
    //psf
    public static final int b=1;
    //psvm
    public static void main(String[] args){
        //new Date();
        int[] arr=new int[4];
        arr[0]=11;
        arr[1]=56;
        arr[2]=33;

        //fori
        for (int i = 0; i < 5; i++) {
            System.out.println(i);
        }
        //

        //iter
        for (String arg : args) {

        }
        //inn
        if (args != null) {

        }
        //ifn
        if (args == null) {

        }
    }
}
