Im trying to write below code from the documentation and the google search

public class AwsECRTest {
    
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ListTagsForResourceRequest request = new ListTagsForResourceRequest();
        request.setResourceArn("arn:aws:ecr:us-east-1:45454512:repository/testrty");
                   
        ListTagsForResourceResult r(ListTagsForResourceRequest request);           
                   
        System.out.println(r.getTags());   
    }

this is the doc link : https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-ecr/src/main/java/com/amazonaws/services/ecr/AmazonECR.java

You're trying to create an object r of type ListTagsForResourceResult and call a method r() simultaneously, unfortunately that's not going to work in Java.

The ListTagsForResourceResult object should be returned from a method call from an instance of the AmazonECR client, so iou'll need to set up an AmazonECR to interact with your ECR repository first, and then call the listTagsForResource() method on the client with your request as an argument:

public class AwsECRTest {

    public static void main(String[] args) {
        
        AmazonECR ecr = AmazonECRClientBuilder.defaultClient();
        
        ListTagsForResourceRequest request = new ListTagsForResourceRequest();
        request.setResourceArn("arn:aws:ecr:us-east-1:45454512:repository/testrty");
        
        ListTagsForResourceResult result = ecr.listTagsForResource(request);
        
        System.out.println(result.getTags());
    }
}
