Why doesn't a character increment in System.out.println()?

Question

char char1 = \'a\';   
System.out.println(char1);      //prints char 1
System.out.println(char1+1);    //prints char 1
System.out.println(char1++);     //prints char         


        

Answer 1

try this.

System.out.println(char1);
System.out.println(++char1);
char1 += 1;
System.out.println(char1);

instead

char1 = a;   
System.out.println(char1);
system.out.println(char1+1);
char1 += 1;
System.out.println(char1);
