if(kiloliters > 1000 && kiloliters < 10000){ //test if the inputted number is in between 1000 and 10000
   kiloliters = (kiloliters + 150)/140;
   System.out.println("The health is %.2f",kiloliters);

If you want to print by providing `format` containing placeholders and `values` for them as other parameters use `System.out.format` or `System.out.printf`. — Pshemo, Nov 23 '21 at 21:10
`System.out.printf("The health is %.2f%n", kiloliters);` Mind the `%n` newline. — Joop Eggen, Nov 23 '21 at 21:12

Java println() is the original "print text" method. You can use it like this:

System.out.println("The health is " + kiloliters);

printf() is a newer addition to Java; it allows "formatted printing" like C, C++ and C# (among many others). You can use it like this:

System.out.printf("The health is %.2f",kiloliters);

Yet another option is String.format():

System.out.println(String.format("The health is %.2f",kiloliters));

... or since Java 15 non-static [`String#formatted(Object... args)`](https://docs.oracle.com/en/java/javase/15/docs/api/java.base/java/lang/String.html#formatted(java.lang.Object...)) for instance `System.out.println("The health is %.2f".formatted(kiloliters));`. – Pshemo Nov 23 '21 at 21:21

You should use System.out.format() instead:

System.out.format("The health is %.2f\n",kiloliters);
