What happens if a Java method does not have a return statement?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\nIf a Java method does not have a return statement and is expected to return a value, the compiler will generate an error.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Can_a_Java_method_return_multiple_values\"><\/span>3. Can a Java method return multiple values?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\nNo, in Java, a method can only return one value.
