I need to sort a list of objects in which the matching items come up and others will go down so. For instance, a list of objects on which all the labels are in alphabetical order except for all the values that start with P that will be put on the top of the list.<\/p>\n\n\n\n
I just need to create a new Comparator class instead of creating an anonymous Comparator, like this:<\/p>\n\n\n\n
Collections.sort(result, new Comparator< MyObject>() {\n @Override\n public int compare(final MyObject o1, final MyObject o2) {\n \n \/\/ Special case to put \"P\" in front of the list\n if(o1.getLabel().startsWith(\"P\")) {\n return o1.getLabel().startsWith(\"P}\")? o1.getLabel().compareTo(o2.getLabel()): -1;\n } else {\n return o2.getLabel().startsWith(\"P\")? 1: o1.getLabel().compareTo(o2.getLabel());\n }\n \n }\n});<\/code><\/pre>\n\n\n\nOn which MyObject is defined in this way:<\/p>\n\n\n\n
class MyObject {\n private String label;\n private String value;\n \n \/\/ getter an setter\n}<\/code><\/pre>\nShare this:<\/h3>
