Double method Can't return decimal or rational values.

Question

I wrote this code. But double method doesn't return any thing. I wrote this code in eclipse

static double PSCH(int a,int b){
int v = a-b;
double d = Math.abs(v/a);
return d;
}

Type this in Scanner : 3800 1200000 1200000 20 4800

Answer 1

I don't know Java so well, but if we want to see the result of PSCH(R_Ly,R_Ty); shouldn't we write:

System.out.println(PSCH(R_Ly,R_Ty));

I only see PSCH(R_Ly,R_Ty);

What program is this anyway?

Answer 2

you should print it:

System.out.println(PSCH(R_Ly,R_Ty));

Answer 3

Result in eclipse is :

write last year usd price in rial : 3800
write last years salary : 1200000
last year salary in usd is : 315

write current salary :1200000
write percentage of salary increment : 20
write current usd price : 4800
salary change of 20 percent in usd is : 50

current salary in usd : 250
salary change in USD after adding increment is : 300
percentage of salary changes is :

🔹This line(last) related to that double method code :
👉🏿 percentage of salary changes is :
