3 part sum of three number divide by fourth number

This java program is able to calculate result in decimal value, you only have to change 8 line of previous program from(double A,B,C,D,total;) to ( Float A,B,C,D,total;).
In this program we take four input number from user -A, B, C, D.
hear A, B, C are added and divided by D,this is the hole detail of program.
