For Character data type, value NULL is equivalent to “empty string ‘’. T/F Solution For Character data type, value NULL is equivalent to empty string is TRUE \'\\u0000\'is the default value for a character. It\'s decimal equivalent is 0. When you are declaring some char variable without initializing it, \'\\u0000\' will be assigned to it by default. java program: public class Test { char c; public static void main(String args[]) throws Exception { Test t = new Test(); char c1 = \'\\u0000\'; System.out.println(t.c); System.out.println(c1); System.out.println(t.c == c1); } } This code will printtruefor the last print here in above code \'\\u0000\' stands for null . So if you print an uninitialized char variable , you\'ll get nothing..
