How can you determine the maximum possible number stored in an int data type?

In Java, the maximum value for the int type can be determined in several ways:

1. Using the constant from the wrapper class Integer:

int maxInt = Integer.MAX_VALUE;
System.out.println(maxInt); // 2147483647

2. Calculating manually, considering that int is a 32-bit signed type, the maximum value is 2^31 - 1:

int maxInt = (int) Math.pow(2, 31) - 1;
System.out.println(maxInt); // 2147483647

3. Using bitwise operations:

int maxInt = (1 << 31) - 1; // shift 1 left by 31 bits, minus 1
System.out.println(maxInt); // 2147483647

The first method is the simplest and most reliable, as it uses the standard constant.
