Answer: In java the symbol "+" operator is used to perform string concatenation.
Explanation:
String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.
An example of String concatenation is as follows:
int age = 10;
System.out.println("The boys age is " + age);
Output:
The boys age is 10.
here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.

Explanation:
Loops are used to execute the part of the code again and again until the condition is not true.
In the programming, there are three loop
1. for loop
2. while loop
3. do-while loop
The syntax of for loop:
for(initialize; condition; increment/decrement){
statement;
}
The syntax of while loop:
initialize;
while(condition){
increment/decrement;
}
In the while, we change the location of initializing which comes before the start of while loop, then condition and inside the loop increment/decrement.
