Hello, 

Kung fu, karate, judo and taekwondo are all really good styles of martial arts in itself. I'll be crisp, and short in this differentiation.

• Kung fu is a very vast form of martial art. It can be analogous to as physics in the category of science. Northern kung fu, southern kung fu and their further branches. It's too vast to put up in words here. It has different styles using different principles. 
• Karate is a Japanese form which is said to be evolved out of Chinese martial arts when some Japanese fishermen got lost and found their way to China, and came back with Karate. 
• Judo is a martial art which focuses on throws and locking them down rather than using punches and kicks. It is a Japanese art founded in 1882 by Kano Jigoro. 
• Taekwondo is a Korean martial art considered to be a very effective and agile art. It focuses on kicking techniques, and was developed in the ‘40–’50s by various different martial artists who combined techniques of Karate, Kung fu and some of traditional native Korean arts.

Hope this helps.....
