Health is the meter of endurance in all versions of Minecraft. A player's health is represented by the number of hearts he/she has. It measures the damage taken by mobs, TNT, or anything else which damages a player (only in Survival Mode and Adventure Mode).
The health bar is located beside the Hunger bar, and above the Experience bar. When a player's hunger bar is at 9 (or completely full), they will slowly regain health. When health is at 4 hearts or less, the health bar will start shaking. The health bar won't regenerate if there are 7.5 hearts or less. The speed at which a player's health regenerates varies, depending on the Difficulty setting. When full, a player's health bar has 10 hearts, which is equal to 20 points of health, as 1 heart counts as 2 points of health.
Death occurs when a player has lost all of their health. A screen will appear and offer the choice of either respawning (going back to the original spawn point, or the last bed they slept in) or returning to the main menu (the death screen will still be there upon re-entering the world). Hardcore Mode does not offer the option of respawning. Players can either delete the world or go into spectator mode after they have died.
This is a table showing how much health each mob has. When their health runs out, they die and may drop items. Mobs can die from lava, fall damage, drowning, suffocation, damage from a player, or damage from other mobs. For example, a creeper may attack a skeleton if its arrow hits the creeper.
