Use of the IF statement: Multi-use for range judgments

Switch statement: Arithmetic, judging a few specific situations

The While statement uses the
int x4=1;

Process Control statement: For Loop
int sum1=0;
for (int x6=0;x6<=10;x6++) {

System.out.println ("= = = Double for loop print multiplication table");

}
}
Break: Leave the current loop
System.out.println ("=======");
for (int q=0;q<10;q++) {
