package scanner;

public class LeftMove {

public static void main(String[] args) {

int i = 1;

System.out.println("i 右移两位：" + (i>>2) ); //0

System.out.println("i 左移两位：" + (i<<2) ); //4

for (int j = 0; j < 4; ++j) {

int  result  = 1 << ((j + 2) % 4);

//  "<<"为左结合性

System.out.println("1 << ((" + j + " + 2) % 4)) = " + result);
