You can practice these operators using below simple programs.

Arithmetic operators

public class Operators1 {

     public static void main(String[] args) {
         
          float a = 523f;
          float b = 10f;
         
          System.out.println("a = " + a );
          System.out.println("b = " + b );
          System.out.println("a + b = " + (a+b));
          System.out.println("a - b = " + (a-b));
          System.out.println("a / b = " + (a/b));
          System.out.println("a * b = " + (a*b));
          System.out.println("a % b = " + (a%b));
         
     }
}

Compound assignment operator

class Apple{
    
public static void  main(String args[]){

     double x= 5,y= 100;

     x+=y;     //x=x+y
     System.out.println(x);

     x-=y;     //x=x-y
     System.out.println(x);

     x*=y;     //x=x*y
     System.out.println(x);

     x/=y;     //x=x/y
     System.out.println(x);

     x%=y;     //x=x%y
     System.out.println(x);
     //in this situation the value of x is changing line by line.

}
}

Increment and decrement operators

public class Operators2 {

     public static void main(String[] args) {
         
          int a = 5;
         
          System.out.println("a = " + a );
          System.out.println("++a = " + ++a);
          System.out.println("a++ = " + a++);
          System.out.println("a = " + a );
     }
}

Relational operators

public class RelationalOperatorDemo {

 public static void main(String[] args) {

  int a = 10;
  int b = 5;

  System.out.println("a : " + a);
  System.out.println("b : " + b);
  System.out.println("a=b : " + (a == b));
  System.out.println("a>b : " + (a > b));
  System.out.println("a!=b : " + (a != b));

 }
}

Logical operators

public class LogicalOperatorDemo {

 public static void main(String[] args) {

  int a = 10;
  int b = 5;
  int c = 1;

  System.out.println("a : " + a);
  System.out.println("b : " + b);
  System.out.println("c : " + c);
  System.out.println(a > b && c > a);
  System.out.println(a > b && !(c > a));
  System.out.println(a > b || c > a);

 }
}

Conditional operator

public class Operators5 {

     public static void main(String[] args) {
         
          int a = 10;
          int b = 5;
         
          System.out.println("a : " + a );
          System.out.println("b : " + b );
          System.out.println("a > b : " + ((a>b)? true :false ));
     }
}

This operator is like if else statement. You can do this one as follows example also.

public class Operators5 {

     public static void main(String[] args) {
         
          int a = 10;
          int b = 5;
         
          System.out.println("a : " + a );
          System.out.println("b : " + b );
         
          if(a>b){
              System.out.println(true);
          }
          else{
              System.out.println(false);
          }   
     }
}

Bitwise compliment

class Apple{
    
     public static void  main(String args[]){
    
          int x = 10;
          int y = ~x;
    
          System.out.println(y);
     }
}

Try these examples to get an experience of operators.

class Apple{

     public static void main(String args[]){
         
     System.out.println( 10+20+ " Add" );
     System.out.println( "Add " + 10+20 );
     System.out.println( "Add " + (10+20) );

     }
}

/*In the second print line 10+20 is got as a string*/
