Int x = 0x80000000; Here, x value is in Hexadecimal and if we convert into in decimal -2147483648. If we convert into in binary, the value is 1000 0000 0000 0000 0000 0000 0000 0000. x = x >>> 31; X is stored using 32 bit 2's complement form. By this Unsigned right shift operation, Before: 1000 0000 0000 0000 0000 0000 0000 0000. After: 0000 0000 0000 0000 0000 0000 0000 0001. |

int x = 0x80000000; 'x' in the value 0x80000000; indicates it as a hexadecimal value. |

Binary equivalent of 0X80000000 is 10000000000000000000000000000000. In int data type if 32nd bit is off, then decimal equivalent is positive and if 32nd bit is on then the equivalent is negative. |

If you convert 0x80000000 (which is in hexadecimal form) to decimal form, it gives 2147483648. But, the range of integer in java is -2147483648 to 2147483647. Since, the converted decimal value exceeds the range(positive value) of integer, it takes the negative value and the values go in a cycle from positive to negative. As the converted decimal value exceeds the integer range by 1, the 1st value from -2147483648 is taken, which is -2147483648. |
