String File = args[3]; // <------ it says this is the error ???
String value = args[7];
boolean Block1 = args[4].equalsIgnoreCase("value1");
boolean Block2 = args[4].equalsIgnoreCase("value2");
boolean C5 = args[5].equalsIgnoreCase("Value3");
boolean C = args[5].equalsIgnoreCase("Value4");
boolean S = args[6].equalsIgnoreCase("Value5");
boolean Del = args[6].equalsIgnoreCase("Value6");
boolean Y = args[6].equalsIgnoreCase("value7");
boolean N = args[6].equalsIgnoreCase("value8");
 
if (label.equalsIgnoreCase("Commander") && sender.hasPermission("permissionhere")){
if(args.length == 0 || args.length > 2){
 
}else if (args[0].equalsIgnoreCase("Editor")){
if(args.length == 1){
 
}
if (args.length == 2){
if(args[1].equalsIgnoreCase("Show")){
 
}
 
 
}else if(args[1].equalsIgnoreCase("Fix")){
if(args.length > 7){
 
}else{
if(!Bukkit.getWorlds().contains(File)){
 
}else{
if (Block1){
if(args.length != 4){
 
}else{
if(C5){
 
}else{
if(C){
if(args.length != 5){
 
}
if(Y){
 
}
if(N){
 
}
}
}
}
}else
if (Block2){
if(C5){
 
}else
if(C){
 
if(!Y && !N){
 
}else{
if(Y){
 
}
if(N){
 
}
}
}
}
}
}
}
}
}else if(label.equalsIgnoreCase("Commander") && !sender.hasPermission("Permissionhere")){
 
}
 
return false;

Do an argument check

 

check the length of an array

An array is an object that consists of elements. It has its own size and elements can be get by its index in the array.
["HI!","HELLO!","HEY!"]
In the array above, the index of "HI!" is 0 and the index of "HELLO!" is 1 etc.

By using array[index] in java, you can get elements by its index. If the index is larger or equal than its length, it means it exceeds its possible length and throws an arrayindexoutofboundsexception.
You need to check it with args.length

 

when i try to type in a command it says the error.
and i thought i already checked the if the args.length == 0 and if its higher than its limit.

 

Rename File to FileTest

 

still get the same error on the same line.

 

A3O2
You're trying to get a nonexistenting index in an array.

 

im slightly lost as it is almost 2am but i will try sleeping see if i figure it out in the morning.
