You can use folowing code to convert -

String strBoolean = "true";

//Do the String to boolean conversion
boolean theValue = Boolean.parseBoolean(strBoolean);
System.out.println(theValue);

Hi xdshi,
My requirement is source column data type is string and data like true,false
but target column data type is boolean.
I converted string to Boolean using this function
"Boolean.parseBoolean(row3.column_name) "

Hi,
If your Input is "true or false", it is totally OK. Maybe the following expression is also a good option

Boolean.valueOf(row3.column_name)

.

Hello,

We would convert data type String to data type boolean with "true or false" in talend.

Usually, we will use Java ternary operator in tMap to do it.

What's your purpose of Source - T/F (datatype string) Target - T/F (Boolean)?

Best regards
