5
int MAX_VALUE = Integer.MAX_VALUE;6
System.out.println(MAX_VALUE); // 21474836477

int MAX_VALUE_2 = (int) Math.pow(2, 31);9
System.out.println(MAX_VALUE_2); // 214748364710
11
int MAX_VALUE_3 = -1 >>> 1;12
System.out.println(MAX_VALUE_3); // 214748364713
14
int MAX_VALUE_4 = ~0 >>> 1;15
System.out.println(MAX_VALUE_4); // 214748364716
