问题 In the following test_if2() works as expected but test_if not. The difference is that in test_if() I do a variable assignment. Where is the error? test_if() { declare file_path if [[ -n ${file_path=$(echo "")} || -n ${file_path=$(echo "Hi")} ]]; then echo Non null: ${file_path} else echo null fi } test_if2() { declare file_path declare greet="Hello" if [[ -n $(echo "") || -n $(echo "Hi") ]]; then echo Non null else echo null fi } test_if #prints null test_if2 #prints Non null 回答1: Use :=

问题 I want my application to check which language the phone is using. This if statement is supposed to do that: if (Locale.getDefault().getLanguage().equals("en")) { yourYesResponse = "That is great " + usersName + "!"; } else if (Locale.getDefault().getLanguage().equals("fr")) { yourYesResponse = "C\'est bon " + usersName + "!"; } But even if my device is set to French it still displays the English. Is there anything wrong with this if statement and if yes, then what? EDIT: Thanks for the help.
