Problem and solution:
LogCat:
Or you can using this code:
Problem and solution:
try {
int [] i = {1};
int z = i[5];
} catch (ArrayIndexOutOfBoundsException e) {
String s = e.toString(); // s == java.lang.ArrayIndexOutOfBoundsException
// try to testing String s for null value
if(s != null)
Log.e("bla", s);
else
Log.e("bla", "My error text 1");
String s2 = e.getMessage(); // s2 == null !!!!!!!
// you need to testing String s2 for null value , or you get FATAL EXCEPTION: main
// and application will be crashed
String s2 = e.getMessage(); // s2 == null !!!!!!!
if(s2 != null)
Log.e("bla2", e.getMessage());
else
Log.e("bla2", "My error text 2");
// this is OK
e.printStackTrace();
}

The source attachment does not contain the source for the file TextWatcher.class.
You can change the source attachment by clicking Change Attached Source below:
You have to add JDK src.zip path to dialog as on image below.
[caption id="attachment_1091" align="alignleft" width="282" caption="class file editor source not found Eclipse warning"][/caption]
Or go to Project > Properties > Java Build Path > Libraries
Expand JRE System Library. Expand rt.jar.
Select Source attachment and double click or Edit.
Type path the source code file (External File…) and press OK.

[caption id="attachment_1105" align="alignleft" width="300" caption="Java JRE deifiniton path in Eclipse"][/caption]
Now if mouse move about keywords String or F3 on keywords and press button in yellow field will opened String.class

Integer, Float, String, List passed as reference in JAVA example source code:
// List passed as reference JAVA
List<Integer>list = new ArrayList<Integer>();
public void fc (List<Integer>listRef){
listRef.add(7);
listRef.add(5);
}
fc(list); // 7, 5
// String passed as reference JAVA
public void mutate(AtomicReference<Object> ref) { ref.set("Goodbye"); }
AtomicReference<Object> ref = new AtomicReference<Object>("Hello");
mutate(ref);
System.out.println(ref.get()); //Goodbye!
String s = (String) ref.get();
// Integer passed as reference JAVA
private static void mutate(AtomicReference<Object> ref) { ref.set(7); }
//public static void main(String[] arg) {
AtomicReference<Object> ref = new AtomicReference<Object>(5);
mutate(ref);
System.out.println(ref.get()); // 7
int n = (Integer) ref.get();
// Float passed as reference JAVA
private static void mutate(AtomicReference<Object> ref) { ref.set(14.8f); }
//public static void main(String[] arg) {
AtomicReference<Object> ref = new AtomicReference<Object>(12.1f);
mutate(ref);
float f = (Float) ref.get();
System.out.println(f); //14.8
