one easy way of doing this is Math.random(); (returns a random num form 0.0 to 1.0) another way of doing this is using java.util.Random class. using this class u can set the seed ur self =)

As a followup to this q How would you use the Math.random(); to generate random integer values (say a integer between 1 and 10)? if you cast Math.random() to become an integer it would have nor eal use because the value would jsut be 0. Is there another way to generate random integers other than using the two previously mentioned methods/class?

I think so Math class also has a Random method that generates a double between 0 and 1. Then you assign that value to an integer. java.util.Random; is better though. You have more control over your (pseudo)random number

The only problem is that we havent covered the method in this topic. Hmm I'll just ask somebody at school 2morrow. No rush. Thx anyway tho.

dan all ways dos thing difrent so heres dans way
the (int) type casts it to an int type rather then double and you times it by 10 to get 0  9 add 1 and you get 1  10

Tony (usually doing opposite of w/e Dan does) creates RandGen object from java.util.Random; and uses .NextInt method to generate integers right away. No type casting
