Java Sourcecode is said to have some variables not initialized.?Question by Imconfused: Java Sourcecode is said to have some variables not initialized.?

driversEdTot=-(carValue*.02);
System.out.println(“Please Enter Your SDIP Total”);
sdip = reader.readInt();
if (sdip>0)
sdipTot=sdip*100.00;
else
sdipTot= -200.00;
System.out.println(“Please Enter Your Years Exp Total”);
yrsExp = reader.readInt();
if (yrsExp >=5)
yrsExpTot = -100.00;
System.out.println(“If ou have front seat air bags please type 1 if not enter any key”);
airbags = reader.readDouble();
if (airbags==1)
airBagTot= -200.00;
System.out.println(“If you have a car alarm please enter 1 if not enter any key”);
antitheft = reader.readDouble();
if (antitheft==1)
antiTheftTot=-(carValue*.01);
totIns = compulsoryTot+collisionTot+comprehensiveTot+bodilyInjuryMax+zipTot+driversEdTot+sdipTot+yrsExpTot+airBagTot+antiTheftTot;
System.out.println(“Your total auto insurance is: “);
System.out.println(totIns);
reader.pause();
}
}
I have no idea what I did wrong in the program I spent hours trying to figure it out.

Answer by ealhmund27
Initialize String Name. So, instead of having String Name; put String Name = “”;
Also, as an aside, I know Java initializes integers and doubles to 0, it’s generally a good idea to explicitly initialize them to zero when you first declare them. Makes for more uniform/better looking code.
Answer by Mose Schrute
it could be one of the following vars:
totIns,carYear,carBrand,collisionTot,comprehensiveTot,bodilyInju,carModel,airbags,carValue,Name
don’t use a variable’s value if it has none yet.
