There are two ways to create String object in Java using new operator Stringstr=newString("TutorialsPoint"); By using string literal Stringstr="TutorialsPoint"; Whenever we call newString() in Java, it will be on the heap An object is created in memory and the string literal goes into the String Constant Pool (SCP). For objects, JVM uses SCP, which is for efficient memory management in Java. Unlike other Java objects, they do not manage String objects in the heap area, but

What is the role of string constant pool and buffer pool in JAVA

1 Constant pool Constant pool is divided into two types, one is the static constant pool in the .class file, and the other is the runtime constant pool formed by loading the static constant pool in the .class file into the JVM. 1.1 Static constant pool The constant pool in the .class file can be regarded as an array. Some constants are stored in the array. When this constant needs to be used in a bytecode instruction, it is accessed through the index of the array. Look at the following code: Stringm="hellohellohellohellohello";Stringn="hellohellohellohellohello"; it will be in bytecode
