Replace all text between brackets Java-CodePudding

I have String

String test = "
    test_one {
    Lorem Ipsum is simply dummy text of the printing and typesetting industry.
    }
    
    test_two {
    Lorem Ipsum is simply dummy text of the printing and typesetting industry.
    }
    
    test_three {
    Lorem Ipsum is simply dummy text of the printing and typesetting industry.
    }
"

I need replace whole text between brackets in 'test_two' or 'test_three' with another text ex "This is my text";

Expected output:

String test = "
        test_one {
        Lorem Ipsum is simply dummy text of the printing and typesetting industry.
        }
        
        test_two {
        Lorem Ipsum is simply dummy text of the printing and typesetting industry.
        }
        
        test_three {
        **This is my text**
        }
    "

We can do a regex replacement with dot all mode enabled:

String test = "test_one {\nLorem Ipsum is simply dummy text of the printing and typesetting industry.\n}\ntest_two {\nLorem Ipsum is simply dummy text of the printing and typesetting industry.\n}\n\ntest_three {\nLorem Ipsum is simply dummy text of the printing and typesetting industry.\n}";
test = test.replaceAll("(?s)\\btest_three \\{.*?\\}", "test_three {\nThis is my text\n}");
System.out.println(test);

This prints:

test_one {
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
}
test_two {
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
}

test_three {
This is my text
}
