is there any way to change the if & else if statements in this code?

Question

System.out.println("Please select the unit\n 1-kilogram(kg)\n 2-gram(g)\n 3-milligram(mg)\n 4-ounce\n 5-pounce(oz)");
int convin = tony.nextInt();
System.out.println("Input value:");
int val = tony.nextInt();
System.out.println("");
System.out.println("Convert to?\n 1-kilogram(kg)\n 2-gram(g)\n 3-milligram(mg)\n 4-ounce\n 5-pounce(oz");
int convout = tony.nextInt();

if (convin == 1 && convout == 1){
int ans = val*1;
}

Sorry about delay. That's rough generic example. Just change your variables to whatever suits what you're doing and input your calculations in the right spots. I commented it some for ya.

Answer 2

I would create a class and create methods for each of the 5 conversions. Then you can just feed the source unit type/value to the methods and have the converted number returned to you. Doing this also allows you to reuse your code later without having to rewrite it.

Give me a few mins and I'll type up some code in the playground for you to use as an example.
