How to change if/else statement to switch statement

Question

I feel like an idiot not being able to figure this out. Can someone please assist me in making this into a switch statement?

if (nextInput.equals("*"))
    f = new Fraction(f.times(f1));
else if (nextInput.equals("+"))
    f = new Fraction(f.times(f1));
else
    f = new Fraction(f.minus(f1));

String text = "";

switch(text)
{
case "*":
   f = new Fraction(f.times(f1));
   break;
case "+":
   f = new Fraction(f.times(f1));
   break;
default :
  f = new Fraction(f.minus(f1));
}

Switch accept String in jdk 7 or higher

Something like this you need

String x="";           
 switch(x)       
 {        
case "*":f = new Fraction(f.times(f1));break;        
case "+":f = new Fraction(f.times(f1));break;        
default:f = new Fraction(f.minus(f1));            
}

Note: switch Strings will only work in jdk7 and or higher versions

You should read the documentation. Try this:

switch(nextInput){
    case "*":
        f = new Fraction(f.times(f1));
        break;
    case "+":
        f = new Fraction(f.times(f1));
        break;
    default:
        f = new Fraction(f.times(f1));
}
