B4J Question inline-java lambda expressions

[khaleel]

this inline code generates the following error. How can I overcome this ?

-----------------------------------------------------------------------
the code
-------------------------------------------------------------------------
public void Sync2TblH(TableView table1,TableView table2) {
ScrollBar t1 = this.findScrollBarH( table1);
ScrollBar t2 = this.findScrollBarH( table2);
t1.valueProperty().bindBidirectional( t2.valueProperty());
table1.getColumns().stream().forEach((c) -> {
System.out.println("Column: " + c);
});

-----------------------------------------------------------------------
the error:

the last line says:
'use -source 8 or higher to enable lambda expressions'
how to do that ?

In the B4J IDE, go to Tools>Configure Paths and select a JDK of 8 or higher for the javac.exe option. If you don't have one installed, install one.

I already have one cand configuered correctly :
C:\Program Files\Java\jdk1.8.0_91\bin\javac.exe

I think it has something to do with java compiler options '-source 8' when B4J IDE compiles the code.but I dont know how to force that option from B4J IDE .

You can't. Only Erel can and he hasn't, apparently: https://www.b4x.com/android/forum/threads/java-version-and-lambda-expressions.55596/
