Math.random()

Random is the function of math class that is available in lang package it will generate a number between 0 & 1 randomly.

0 can be generated but 1 can’t be generated.

For generating between 100&580

X=(int)(Math.random*481+100);

Y=(int)(Math.random*481+100) ;

100 is the starting point where as 481 is the difference plus 1.

*Color c=new Color(r,gr,b);

int r=(int)(Math.random()*256);

int gr=(int)(Math.random()*256);

int b=(int)(Math.random()*256);

Ques:-Write a program which generates a different names with different colors randomly.
