Java String Pool:Java employs a dedicated memory section referred to as the “string pool” or “string constant pool.” This pool is used to store distinct string literals. When a novel string literal is generated, Java checks whether it already resides in the pool. If it does, the new ...
"Hello World"is called aStringliteral. In a Java program, everything between two double quotes is aStringliteral. Literals are implemented as instances of String class. As you can see, you can conveniently initialize aStringObject like a primitive type, e.gint i = 0;. There is no need t...
