So I was just wondering if there was a way to print out multiple char variables in one line that does not add the Unicode together that a traditional print statement does.
For example:
char a ='A';
char b ='B';
char c ='C';
System.out.println(a+b+c); <--- This spits out an integer of the sum of the characters
System.out.println(a+""+b+""+c);
or:
System.out.printf("%c%c%c\n", a, b, c);
You can use one of the String constructors, to build a string from an array of chars.
System.out.println(new String(new char[]{a,b,c}));
The println() method you invoked is one that accepts an int argument.
With variable of type char and a method that accepts int, the chars are widened to ints. They are added up before being returned as an int result.
You need to use the overloaded println() method that accepts a String. To achieve that you need to use String concatenation. Use the + operator with a String and any other type, char in this case.
System.out.println(a + " " + b + " " + c); // or whatever format
This will serve : System.out.println(String.valueOf(a) + String.valueOf(b) + String.valueOf(c));.
System.out.println(new StringBuilder(a).append(b).append(c).toString());
System.out.print(a);System.out.print(b);System.out.print(c) //without space
String, not to add three chars together. Acharis an unsigned 16-bit integer.
