Converting Datatypes in Java

Converting Datatypes in Java

• Converting String to Integer

String s = "Hello";

int x = Integer.parseInt(s);

• Converting Integer to String

int i = 50;

String x = String.valueOf(i);

• Converting Char to String

char c = 'o'

String x = String.valueOf(c);

• Converting String to Char

String s = "h";

char c = s.charAt(0);

You can use for loop to take the full characters from a string

eg - 

String s = "hello";

char c;

for(int i =0;i<s.length();i++)

{

      c = s.charAt(i);

      System.out.println(c);

}

• Converting Char to Integer

 String str="1234";
      for(int i=0;i<str.length();i++)
      {
         char c=str.charAt(i);
         Character.getNumericValue(c);
         System.out.println(Character.getNumericValue(c));
         System.out.println(Integer.parseInt(str.valueOf(c)));
      }

• Converting Integer to Char

int i1 = 'a';

int i2 = i1;

char c1;

char c2;

c1=i1;

// To avoid a potential compiler warning, use a cast `char`.

c2 = (char) i2
