Hi all...
I have piece of code like this..
char charArray[] = { 'b', 'i', 'r', 't', 'h', ' ', 'd', 'a','y'};
byte byteArray[] = { (byte) 'n', (byte) 'e', (byte) 'w',
(byte) ' ', (byte) 'y', (byte) 'e',
(byte) 'a', (byte) 'r' };
StringBuffer buffer;
String s, s1, s2, s3, s4, s5, s6, s7, output;
s = new String( "hello" );
buffer =
new StringBuffer( "Welcome to Java Programming" );
// use the String constructor
s1 = new String();
s2 = new String( s );
s3 = new String( charArray );
try {
s4 = new String( charArray, 6, 4 );
}
catch( StringIndexOutOfBoundsException ex ) {
System.out.println( "out of exception" );
}
s5 = new String( byteArray, 4, 4 );
s6 = new String( byteArray );
s7 = new String( buffer );
output = "s1 = " + s1 +
"\ns2 = " + s2 +
"\ns3 = " + s3 +
"\ns4 = " + s4 +
"\ns5 = " + s5 +
"\ns6 = " + s6 +
"\ns7 = " + s7;
When i try to compile this, an error "variable s4 might not have been
initialized" occurs.
Would someone like to explain me why?
Thankyou in advance.
