Example: Math.FMA is not available in Java 8 but we want to use it
regularly.
1) Sub-Project FMA8
public class FMA {
public static float fma(float a, float b, float c) {
return a * b + c;
}
public static double fma(double a, double b, double c) {
return a * b + c;
}
}
2) Sub-Project FMA for Java 11 and better
public class FMA {
public static float fma(float a, float b, float c) {
return Math.fma(a, b, c);
}
public static double fma(double a, double b, double c) {
return Math.fma(a, b, c);
}
}
3) Main Project dependencies as per Java Version
dependencies {
if (JavaVersion.current() == JavaVersion.VERSION_1_8) {
implementation project(':FMA8')
} else {
implementation project(':FMA')
}
}
So the Main Project will be able to call FMA.fma(a, b, c) despite the
Java Version.
