It goes at the end of every statement, however is not required at the end of blocks.
Ex/
if(condition){
}
// no semi-colon needed here.
The {} is the scope or block of the if statement.
Another example/
void myMethod(){
int a = 3;
// semi-colon needed
} // no semi-colon needed

You put them after every statement. Basically everything is a statement that isn't a code block in Java. Code blocks are written with these curly braces { }
code blocks can be class definitions, function definitions, loop blocks, if, else and switch blocks
for example:
class A {
}
or
if(condition) {
}
are code blocks
other than those are statements, like variable definitions, operations with variables, function calls, etc.
i.e.
int a;
double b = 3.0;
a = 2;
a = b;
and so on

I don't know about Java, but I think you put that at the end of every line.

It still depends whether or not your talking about a block or statement.
Declaration of a String? Yea.
Creating a method with a String return type? No.
Returning a String? Yea.
Best to just know, not for blocks, yes for statements, so you don't need to keep asking yourself.

You should use it at the end of the statement. Like declaring variables. At the end of operations like arithmetic int x=5+3;
