Why int type method is allowing character type as return value? [duplicate]

Answer 1

public static int getValue(char character){
    return character;//<-- unicode value is being returned, e.g. char 0 -> int 48
    // char ranges from 0 - 65535
}

From JSL:

5.1.4. Widening and Narrowing Primitive Conversion

The following conversion combines both widening and narrowing primitive conversions:

byte to char

First, the byte is converted to an int via widening primitive conversion (§5.1.2), and then the resulting int is converted to a char by narrowing primitive conversion (§5.1.3).
