IntelliJ IDEA之常用模板

public class templateTest {
    //模板一：psvm
    public static void main(String[] args) {

        //模板二：sout
        System.out.println("Hello!");
        //模板二的变形：soutp/soutm/souv/xxx.sout
        System.out.println("templateTest.main");
        System.out.println("args = " + args);
        int num1 = 10;
        System.out.println(num1);

        //模板三：fori
        String[] arrays = new String[]{"Jacob", "Lee"};
        for (int i = 0; i < arrays.length; i++) {
            System.out.println(arrays[i]);
        }
        //变形：iter
        for (String array : arrays) {
            System.out.println(array);
        }
        //变形：itar
        for (int i = 0; i < arrays.length; i++) {
            String array = arrays[i];
        }

        //模板四：array.for
        ArrayList<Integer> array = new ArrayList<>();
        array.add(12);
        array.add(34);
        array.add(56);

        for (Integer integer : array) {
        }

        //变形：array.fori （正序遍历）
        for (int i = 0; i < array.size(); i++) {

        }

        //变形：array.forr（倒序遍历）
        for (int i = array.size() - 1; i >= 0; i--) {

        }

        //模板五：ifn
        ArrayList<Integer> list = new ArrayList<>();
        list.add(12);
        list.add(34);
        list.add(56);
        if (list == null) {

        }

        //变形：inn
        if (list != null) {

        }

        //变形：xxx.nn/xxx.null
        if (list != null) {

        }

        if (list == null) {

        }
    }

    //模板六：prsf
    private static final int n= 3;
}
