Assignment operator (geritilent software - Jiuye training)

Extended assignment operators

Operator ：

+=

-=

/=

%=

grammar ：

Operands 1 += Operands 2 Operands 1 -= Operands 2 Operands 1 *= Operands 2 Operands 1 /= Operands 2 Operands 1 %= Operands 2

characteristic ：

Binary operator .

Operational rules ：

    a += b

    amount to ：

    a = a + b;

Example 1：

publicclass Demo {     publicstaticvoid main(String[] args) {         inta = 5;       System.out.println(a += 2);       System.out.println(a -= 2);       System.out.println(a /= 2);       System.out.println(a %= 2);        } }

Calculation results ：

Example 2：

publicclass Demo {     publicstaticvoid main(String[] args) {         byten1 = 5;       n1 += 2; // Perform automatic implicit forced rotation       System.out.println(n1);           } }
