Example 2 – chars() In this example, we will create a StringBuilder object with some initial string literal. dot net perls. All variables of type int use 32 bits. The characters are copied into the char array starting at index dstBegin and ending at dstBegin + (srcEnd-srcBegin) – 1. String to char Conversion: Sometimes, we obtain the values in string fomrat in Java. Using typecast operator; Using forDigit() method; Using typecast operator Java Data Types.
