Once a string has been constructed, itneverchanges. Methods that in some languages might change the string, such astoUpperCase(), in Java create a newStringwith the desired changes applied. AStringis immutable, period, full stop (unless you bring in some native code using JNI to modify one...
package p.b; import org.immutables.value.Value; @Value.Immutable public interface B { String getText(); } Why does it produce p.b.ImmutableB.java rather than p.b.BBuilder.java for sourceCompatibility=1.9? It would be great if you can investigate source-path which Gradle is using to comp...
The lie that it is more performant than Java or C# I love this argument because depending on what you want to prove, you can have a different result. I’ve done myself two benchmarks when comparing Go to Java. In one of those tests, Java was about 10% faster because the JIT did ...
