Key1 = new String[]{"Soekarno", "Soeharto, "Habibie", "Gusdur", "Megawati", "SBY", "Jokowi"};
String[] Answer1 = new String[7];
Aswer1 = new String[]{" ", " ", " ", " ", " ", " ", " "};
int i;
for (i = 0; i < Key1.length; i++);
 
//Jump to else if
 
else if(textMessageContent.getText().equalsIgnoreCase("First Quiz")){
    replyText(messageEvent.getReplyToken(),"Nama-Nama Presiden RI: \n1. _____ \n2. _____ \n3. _____ \n4. _____ \n5. _____ \n6. _____ \n7. _____");
else if(textMessageContent.getText() == valueOf(Key1[i])) { 
    Answer1[i] = textMessageContent.getText(); 
    replyText(messageEvent.getReplyToken(), "The name of Indonesia's President since independence day:" + Answer1[i]);
